Which way do I turn the distributor?
Turn the distributor in a counterclockwise direction to advance the ignition timing. Do not over-adjust the distributor, as even a slight movement will yield a significant change in the ignition timing.
How does retarding timing affect an engine?
Ignition Retarding. Ignition timing retarding causes the spark plug to fire later in the compression stroke. The effects of retarding ignition timing include reducing engine detonation, which is combustion inside the cylinders after the spark plug fires. This is also known as engine knocking.
Can timing cause Dieseling?
Potential causes Dieseling can occur for several reasons: Similarly, hot vaporized oil gases from the engine crankcase can provide ample fuel for dieseling. Incorrect timing. An engine that runs too hot or too lean may produce an environment conducive to allowing unspent fuel to burn.
Which direction does a Chevy distributor turn?
