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.

Advice 2: 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.
