The operation of a car engine is impossible without a correctly set ignition timing. This is noticeable not only when it is started with a starter, but also when driving. Increased discomfort is created from uneven operation, a drop in engine power, increased fuel consumption and, most importantly, the car begins to behave unstably on the road, it may even just suddenly stall. With a little skill, you can do the setting of the ignition timing on a contactless system yourself.
Secure the car with a parking brake or stop. Set the piston of the 1st cylinder to TDC (top dead center). In this case, the hole on the crankshaft pulley must match the mark (pin) on the timing gear cover.
Remove the cover from the ignition distributor. The slider should be positioned against the input "1" inside it. If not, turn the crankshaft 180 degrees. Set the octane corrector to "0". Tighten the indicator with the bolt to the housing of the ignition distributor so that it coincides with the middle risk of the octane corrector. Slightly loosen the bolt securing the plate to the distributor sensor housing.
Turn the housing carefully, holding the slider against its rotation with your finger to eliminate gaps in the drive, until the tip of the petal on the stator and the red mark on the rotor are aligned. Fix the octane corrector plate with a bolt to the distributor sensor housing.
Replace the cover of the distributor sensor. Check ignition timing according to cylinder 1-2-4-3 order, counting counterclockwise. After setting the ignition timing, check that it is correct in motion.
Start the engine, warm up to operating temperature (80 degrees). On a straight section of the road, moving at a speed of 40 km / h, sharply press the accelerator. If a short-term detonation is felt at a speed of 55-60 km / h, then the moment on the contactless ignition is set correctly. In case of strong detonation, turn the distributor sensor by 0.5-1 division on the octane-corrector scale counterclockwise. If there is no knock at all, then increase the advance angle by turning the distributor sensor clockwise. The scale division corresponds to an angle of 4 degrees on the engine crankshaft.
