Does a timing light measure RPM?
A timing light may be a self-contained instrument, but is sometimes combined with a voltmeter, RPM meter, and a dwell angle meter, or may be incorporated into a more comprehensive instrument such as an engine analyser.
What happens if timing is too advanced?
If ignition timing is too far advanced, it will cause the fuel-and-air mixture to ignite too early in the combustion cycle. This can cause the amount of heat generated by the combustion process to increase and lead to overheating of the engine.
What causes ignition timing to be off?
The ignition timing error is typically caused by damage internally like the pistons or valves inside the engine. A loose or weak engine timing belt that jumps time can cause the ignition timing to be off.

Does advanced timing lean or rich?

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.
Will engine run if timing is off?
If the timing is off, damage can occur. In some engines, called “interference engines,” the consequences can be especially bad. You could end up having to have your engine rebuilt, or even replaced.
