First check the vacuum control of ignition timing. In the 80-ies and early 90-ies of the Ford "Transit" puts the mechanical system of the ignition control. Such designs have proved as unreliable and since the mid 90-ies started to be used unregulated automatic units with electronic control of ignition.
Regardless of the design of the distributor, its serviceability is checked using the tube that supplies vacuum. To check start the engine and warm it up to operating temperature at idle. Then, without changing the speed of the motor, disconnect the vacuum pipe from the inlet of the regulator. Then, attaching to the inlet of any pipe of soft material, use it to create a vacuum. The engine rpm should rise 100-200 rpm. This means that the vacuum controller is defective.
Checking the condition of the vacuum regulator is a very important procedure before adjusting ignition timing. Conceding this point, exhibited the ignition may be incorrect. Unfortunately, this mistake is often made by the employees of service stations. Connect the strobe to the engine so as it says in the instructions attached to it. In most cases, to mount it, connect the lead wires to the terminals on the battery, do not confuse polarity. the induction coil sensor replace the high-voltage wire of the first cylinder.
On the engine, locate the timing marks or graduated scale. Look for them on the crankshaft pulley in front of the power unit or in the window above the flywheel. Often these marks are hidden under a thick layer of dirt and rust, so will clean these places, and if necessary, touch up markers. If the engine has time to cool down, start it and warm again. Then let run at idle. The vacuum hose going to the regulator and disconnect and turn off. Lamp flash strobe aim at the timing marks or scale. When properly exposed to the ignition of the label of the crankshaft and flywheel should be aligned.
If the ignition timing is brought down, and the labels are not aligned, loosen the adjusting bolt of the distributor by removing the locknut. By rotating the distributor housing clockwise or counterclockwise, achieve full alignment marks on the crankshaft and the flywheel.
Take a short ride to check adjustments. Detonation engine is allowed only when sudden acceleration and the duration should not be more than 1 sec. If the engine feed system from the repair, detonation could appear when correctly exposed the ignition. In this case, you need to commit a half-hour trip before the accumulated carbon in the cylinders to completely burn. If after this trip the detonation persists, install a later ignition timing.
Advice 2: How do you set the ignition in the Urals
Adjusted the ignition on the bike contributes to effective operation. Competent adjustment increases the engine power and speed and also saves fuel. On most new motorcycles "Ural" is a modern contactless ignition. Older models can also be converted into this type of ignition, which facilitates the process of adjustment.

Install the crankshaft position top dead center on the compression stroke of first cylinder. Look at this on a long label, available at the crankshaft. Make sure the rotor contact is opposite the inner cap terminal. This contact should be connected to the wire from the spark of the first cylinder.
In that case, if the distributor installed on the engine after it has been repaired, remove the candle of the first cylinder. The hole exit is made from paper tube. Now rotate the crankshaft until the air pushes the cork out of the hole. This point indicates the beginning of the compression stroke in the corresponding cylinder.
Loosen the microprocessor unit, so that it can rotate. Rotate the unit counterclockwise until it stops.
Look at the flywheel marks and align it with the center mark of the motorcycle engine. One label is usually denoted by the letter "B" (top dead center) and the other with the letter "P" (pre-ignition).
Make sure that the ignition system and microprocessor unit is powered-up, which can be verified by the led light bulb.
Slowly rotate the unit and determine the moment when the test lamp goes out. Now securely tighten all fasteners.
After adjusting precise moment of ignition on the experience. Use a test lamp, closing the contacts. When set correctly the ignition light will turn on and off when turning the crankshaft.
When placing plugs having a contact circuit, first check and adjust the clearance between the contact breaker (it should be equal to about 0.5 mm). To the terminal in the low voltage coil connect a test light; the second wire from the lamp attach to ground.
Now rotate the crankshaft to align marks on flywheel and crankcase. Rotate the body of the breaker after releasing the fastening screws. When the warning light flashes, securely fix the body of the breaker. Disconnect the test lamp.
