Advice 1: How to adjust the carburetor on the brand

The engine often called the heart of the car, and the carb – it valve. Indeed, from the correct carb settings depends on many things. It and performance, fuel consumption and CO level.
How to adjust the carburetor on the brand
Instruction
1
You must have sufficient knowledge and skills to ensure that you could correctly adjust the carb. Inspect the carburetor. To adjust it there are two screws. For the number of revolutions meets the first adjusting screw, and for the quality of the mixture the second. Idling adjustment of the engine speed and adjusting the content of co is produced.
2
Make adjustments only at idle, the system which is Autonomous. Only at engine idle speed you can adjust the quality of the mixture using an appropriate screw.
3
Inspect and, if necessary, adjust the ignition system before adjusting the carburetor. The engine should be fully functional. On the failed engine to adjust the carburetor correctly you will fail. If ignition and motor are normal, the adjustment will be successful.
4
If you have correctly adjusted the carburetor, the engine will stall when the voltage is removed from the solenoid. If not, then most likely the diaphragm is a hole leading to excessive consumption of gasoline. When replacing a solenoid valve jet idle speed leave the old factory. Check after adjustment, is clearly in its original position when releasing the throttle returns the throttle.
5
The frequency of rotation of the motor shaft and the adjustment of system idle speed must comply with all the requirements of the user's manual. If you do not comply with the norms specified therein, he will break the engine and will spend a large sum of money for its repair.
6
If you do not have sufficient experience for such type of work, carry out all the necessary procedures only with a specialist. Special attention to after adjusting co content in the exhaust gases is not exceeded.

Advice 2: How to adjust a carburetor on a scooter

In recent years, a trend distribute scooters among adolescents. If they had been a novelty, now it is probably every schoolchild. Scooter has a lot of advantages and almost no disadvantages. First, it is quite easy to manage. Second, it is not as big as a motorcycle. Thirdly, and perhaps most importantly, the scooter does not need rights because it is considered as a bike with an outboard motor from the point of view of traffic rules.

2
Preparations for the work you have done, now starts the actual adjustment.
The first thing you have to adjust the idle screw so the engine kept revving and gloh. In the case where no idle or when they are too low or high tightening or unscrewing of screw to reduce or increase the speed, achieving values of 1800 plus or minus 100 revolutions per minute.
3
You should then fully tighten screw fuel mixture. As a result, the engine should stall. If it does not, check tightness of the system supply air from the air filter.
4
The next thing you do is turn the fuel mixture screw one turn.
5
The next step that you should do is start the engine and adjusting the idle screw to achieve the values of the engine speed around 2500 per minute.
6
Then you should slowly remove the screw of the fuel mixture, achieving maximum engine rpm. But don't twist the screw too much. Two full turns will be sufficient, but no more.
7
After that, you need to re-adjust the idle screw, achieving values of engine speed of about 1800 (plus or minus one hundred revolutions per minute.
8
The final step. Turn the throttle several times and check if the engine steadily holds the number of the idle speed. If everything is in order, the carburetor on your moped is properly configured and you can safely go without fear that it is on the way happens to be any problems.

Advice 4: How to adjust the carb on the "Ural"

If the motorcycle engine called his heart, the carburetor can be rightly called the heart valves. His correct and timely configuration depends not only fuel consumption, but also performance techniques.
How to adjust the carb on the "Ural"
You will need
  • - wooden tube
  • - drill
Instruction
1
Adjust the position of the floats. To do this, remove the carb and flip it over after disconnecting the bottom of the float chamber. If the floats do not lie in the same plane, bend the base of one of them so that the difference between them does not exceed 0,5 mm.
2
Install fuel level, bending the float Tang so that the distance from its outermost edge was 26 mm. Note that this figure is applicable for flat terrain, where the height above sea level not over 1000 m In altitude above this level twice, the benchmark is 28 mm.
3
Adjust the starter. Set the needle to the lowest position. Check out how easy moving the lever on the steering wheel. If necessary, disassemble, lubricate and reassemble it. Install the carburetor in place.
4
Before adjusting the idle speed warm up the engine to operating temperature. Raise the throttle stop screw to increase the engine speed. The screw of the "quality" of the mix to the end, without effort, and then Unscrew it one and a half turns.
5
Along the way, check the ease of movement of the throttle in the slots, check that no excessive backlash in the well. A u-shaped inductor allows by flexion and extension of to some extent to eliminate the backlash.
6
Set the motorcycle on its centre stand, throttle screw gradually lower quantities. Get the frequency of rotation was reduced to the lowest sustainable rate. Then remove the screw "quality" to increase. Again similarly produce a decrease and increase of speed, impoverishing mixture.
7
After you set a minimum speed to drive the screw "quality" on sex trafficking. This will make the engine idle more stable.
8
Within the movement of the throttle from 1/3 to 3/4 (at the turn of the throttle or the lift height) on the engine most affected by the needle position. To determine how true it is selected, after about 25km, stop the bike and remove the spark plug.
9
Note the color of the insulator of the Central electrode. If it is pale gray, raise the metering needle; if it's black, put it. Normal is dark gray or light brown color, indicating that the candle does not overheat.
10
When selected, the needle position, it will be possible to take care of the greater efficiency of the carburetor. You will need to lower the needle one notch.
11
The last stage of adjustment – the correct selection of main fuel jet. Measure the maximum speed prescribed in the standard nozzle. Put into the inlet of the carb tube of wood with drilled canalized. Its diameter should be 20% smaller than the diameter of the inlet. If the rate then considerably decreased, - the performance of the nozzle is large, if diminished performance is small. If a significant speed change has not occurred, the nozzle no need to change.

Advice 5: How to adjust the carburetor for VAZ 21099

Adjusting the carburetor important and responsible part of the work on maintenance of the car. To accomplish this you need certain skills and qualifications, without which this job is best left to professionals.
Carburetor Solex
All front-wheel models of VAZ, including the VAZ – 21099, installed a carburetor type "Solex". The only difference in the diameters of the nozzles depending on engine size. The basic setup of the carb is the idle adjustment.

The carb adjustment is only possible with proper timing and correctly established moment of ignition


Before starting adjustment work you must remove the air filter housing, disconnect the cable choke, the wire of the electromagnetic valve of idling and fuel hoses.

Tools



To perform this operation you will need: spanners 8, 10, 13, Phillips screwdriver, Eclipse.

Carb adjustment



At the beginning of the adjustment is checked and set the fuel level in the float chamber. A ruler or caliper measure the distance from fuel level to the plane of the connector of the carb, it should be 25.5 mm.

To adjust the fuel level with a screwdriver remove the five screws and remove the top cover of the carb. Flip the lid horizontally with the floats up. The gap between the lower ends of the floats and gasket should be the same and 0.5 – 1 mm. If the clearance is not equal or differs from the norm, to handle the tucking of the levers of floats.

Next is adjusting the trigger device. Before adjusting, check the state of the diaphragm, to do this remove the four screws and remove the cover. Aperture with defects must be replaced.

Completely close the choke and pull the stock launcher of the device until it stops. The air valve should be slightly opened to the value of the starting gap of 3 mm. If different from the specified value, loosen the lock nut on the cover and adjust the gap screw.

Once installed on the lid of the carb will need adjustment of air damper. To do this, fully open the choke and fully to drown the handle of the air damper in the car.

Pull the actuator rod out of the sheath until it stops and tighten the screw on the lever of door actuator. To pull the handle actuator in the passenger compartment, the air damper should close completely. Again push the handle – damper should be fully open.

If not, then you need to loosen the bolt securing the thrust shell and move the shell to the air intake valve fully opened and closed.

Adjustment of idling



The idle speed adjustment to achieve a minimum content of toxic substances in exhaust gases. Adjustment is made on a warm engine, with the air cleaner.

As the idle speed adjustment takes place by means of the detector, this work is better to spend on station maintenance


Rotating the plastic adjustment screw of quantity of a mixture set to idle value 750 – 800 rpm. The gas analyzer measured the co content in the exhaust gases. The norm is 1% with a tolerance of 0.3 percent.

If necessary, the size is adjustable WITH a screw, the closed disposable plastic cap. When screwing in the screw the co content reduces, unscrewing increases.

Next, screw the number of restore previous idle and re-check the co content. The adjustment is repeated until the optimal result. After adjustment sharply press the gas pedal – the engine should have no failures to increase the revs and when you release the pedal should not stall.

Advice 6: How to make economical carb

There are many different designs of carb. This device is used to deliver a mixture of fuel and air into the engine. On all gasoline engines used in domestic and imported cars, it is possible to reduce fuel consumption and make the carb more efficient.
How to make economical carb
Instruction
1
The simplest carburetor consists of: float chamber, float, diffuser, nozzle spray bottle and throttle.

Fuel is supplied through a tube from the tank to the camera. In the float chamber is a hollow brass float and rely on the shut-off needle. When the fuel in the float chamber reaches a certain level, the float rises and forces the needle to close the tube, after which the fuel supply to the carburetor is stopped.

During engine operation, fuel consumed, its level in the chamber decreases, whereby the float drops and the needle opens again the pipe and starts the fuel supply. With this system in the float chamber is maintained a constant level of fuel, and this is very important for proper engine operation and fuel management.
2
In order to reduce fuel consumption in a car with a carburetor type engine, you need to buy in a specialized shop so-called repair kit, nozzle size which is less than the standard carb. Kit for a domestic car is likely to cost much cheaper than branded.
3
The nozzle is used to supply fuel from the float chamber to the atomizer. The amount of fuel depends on the type of the jet, namely its shape and size. Consequently, the smaller the engine size, which is calculated on the jet, the less fuel will be supplied to the atomizer, and therefore the fuel consumption will be less.
4
So, in order to reduce the consumption of fuel in the carb, enough to buy the kit with nozzles designed for a smaller engine size. For example, on the carburetor from the VAZ 21011 with an engine capacity of 1.3 liters, you will need to buy a kit for a Taurus with engine capacity of 1.1 liters
5
After the purchase of a suitable kit, remove the carb and disassemble it. Replace the old jets to the new one which is designed for a smaller engine size. Next, assemble the carburetor and install it in place. With proper Assembly and disassembly of carburetor and installing orifices, the fuel consumption should decrease.

Advice 7: How to adjust the carburetor VAZ

The engine is often called the heart of the car, and the carb is a heart valve. On correct setup of the carb determines the fuel consumption, performance, and the level of CO and so on.
How to adjust the carburetor VAZ
Instruction
1
To correctly adjust the carb, you need to have sufficient knowledge and skills. To adjust carburetor has two screws. The first adjustment screw is responsible for the number of revolutions and the second for the quality of the mixture. With their help you can adjust the engine speed to idle and adjust the co content in the exhaust gases.
2
The whole system is idling offline. That is why the regulation only applies to her. Screw the quality of the mixture will govern the mixture is just for idle engine operation.
3
Before adjusting the carburetor, you need to carefully inspect and, if necessary, adjust the ignition system. The engine should be fully functional, as on the failed engine will not be able to properly adjust the carb. If the data is two points meet the standards, it is possible to do the adjustment.
4
If the carb adjustment is performed correctly, then when the voltage is removed from the solenoid, the engine will stall. With the full twist of the screw "quality" of the mixture, the engine should stall. If not, the diaphragm likely has a hole, which lead to excessive consumption of gasoline. Replacing solenoid valve, a nozzle and idle speed leave the old one, i.e. the one that came from the factory. After adjustment check, clearly returns the throttle to its original position when you release the gas pedal.
Useful advice
For summer season you need to put 700 – 800 rpm, for winter - 900 – 1000 rpm.

Advice 8: How to set carburetor for motorcycle

The most common motorcycle carburetors have five basic tools for adjustment. The main adjustments are carried out with their help, additional adjustments are carried out individually, depending on the specific brand of carb.
How to set carburetor for motorcycle
Instruction
1
Find on the body of the carb screw idle mixture. To enrich the fuel mixture a slightly lower idle speed wrap this screw. This screw regulates the work of the carburettor mode throttle opening to¼. On some models of carburetors to enrich the mixture need to Unscrew this screw. Resistant the idle screw can also find on the carb body. It limits the lowering of the spool of the throttle. Tighten the screw to lift the valve core of the throttle and increase engine speed.
2
Adjust the quality of the fuel mixture through the dispensing needle, which can be attached in different positions spring loaded. Adjustments submitted via this needle, affect carburetor operation mode ¾ to full speed. For the enrichment of the fuel mixture install the spring latch in the lower groove. For the lean, move the clip to the top. On some models of carburetors latch is adjustable in 8 different positions. In addition, the needle can be mounted without a latch.
3
The quality of the fuel mixture for the operation of the carburetor in the full stroke, adjust the selection of the main nozzle with the sprayer. The selection of this nozzle will also affect the operation of the carburetor in all modes. In various carburetors needle valve can be positioned both horizontally and vertically. If there are multiple grooves on the shut-off needle float chamber adjust fuel mixture for all operating modes. To impoverish the mixture, move the needle higher, relative fuel level in the float chamber.
4
On carburetors with missing system idling adjustment of spending by the metering needle, main fuel jet, and the thrust of the idle screw. On the carburetors of old patterns and simplified carburetor adjustment run, varying the gap under the throttle valve with fitting-emphasis.
5
Before adjusting the carburetor, run the engine. Start with the IAC. On the cover of the mixing chamber screw the thrust screw until the end. Candle install clean and reliable. The four-stroke engine set later than the ignition. Start the engine and close the hand valve of the throttle. If the engine stalls, start to slowly Unscrew the stop screw the idle speed up until the engine will not be operating steadily with the throttle closed.
6
Then screw the quality (composition) of the fuel mixture will put the maximum engine speed. Then screw the idle speed decrease idle speed until the appearance of signs of unstable operation of the engine. Thus, adjust the carburetor, alternately increasing the revs by a lean condition and reducing the rpm by reducing the size of the gap under the throttle. Upon reaching stable operation of the engine idling at minimum speed, loosen the adjusting screw of quality of a mix in ¼ turn and lock it, preventing displacement of the set position. Note: if the carb is worn, qualitative adjustment of idling to achieve not to turn out.
7
When you adjust the carb on the secondary modes keep in mind that when moving the dispensing needle up will increase the throttle response of the motorcycle and increase fuel consumption. If throttle response and fuel consumption is satisfactory, do not move the metering needle. If the spark plug is clogged with soot, will obecnice fuel mixture, lowering the metering needle one or two grooves. To eliminate detonation and reverse flashes in the carb, raise the needle 1-2 positions.
8
If full-stroke engine does not develop full power, test the operation of the carburetor with a different size main fuel jet. To increase the power of the engine should be set to jet with a capacity 10-20% higher.

Advice 9: How to adjust the carburetor of a chainsaw

For a flawless and long-term operation of a chainsaw is required to periodically adjust the carburetor. This should be done taking into account the specific brand of your device, and standard parameters specified in the technical manual supplied with the saw. The correct adjustment of the carburetor will depend on the efficiency of the entire technical system.
How to adjust the carburetor of a chainsaw
You will need
  • - the manual of a chainsaw;
  • - tachometer;
  • - screwdriver.
Instruction
1
Check device chainsawset forth in technical documentation for it. Determine the location of the jets of the carb and the adjustment screws. The standard carb has usually two or three screw controls the fuel mixture adjustment screw idle speed, and screws the jets high and low speed.
2
To adjust high and low engine speed saw, use the appropriate screws. They regulate the ratio of fuel and air that is determined by the degree of throttle opening. For the lean mixture screw in the corresponding screw clockwise. If necessary, increase the engine speed (i.e. richer mixture), remove the screw by rotating it counterclockwise.
3
Adjustment of idling speed is also carried out by rotating the right screw. Turn the knob in the direction of clockwise to increase the frequency of idling. To reduce engine speed slowly turn the screw in the opposite direction.
4
When adjusting the carburetor , keep in mind that the initial stage of operation of a chainsaw is necessary to keep the factory settings. Exposed the factory settings are calculated for a richer mixture. After hours of work the saw can begin to self-adjust the carb.
5
Run the saw at full speed for 10-20 seconds. Then, Unscrew the needle valve the high speed counterclockwise. Ten seconds with a tachometer check the maximum engine speed and contrast the findings with those specified in the technical passport of the device. Too lean makes the saw "scream"; the excessive enrichment of the mixture of smoke from the muffler.
6
Observe when you change settings caution since a sharp change in the number of high speed greatly affects the power device and the rotation speed of the circuit. The depletion of hot mix leads to unnecessary, excessive rpm, which can lead to damage to the chainsaw down.
