Re: Advance timing??

You won't go wrong using factory specs for initial timing and distributor advance curves.

If your engine is altered from stock, you may need to adjust timing to avoid detonation under load.

That said, many factors affect when and if an engine will "ping" or detonate.

Advancing initial timing will improve starting, IF it was firing too late to begin with.

If your engine has a worn timing chain, timing marks will be out of register. With a well-worn engine, you may have to "play it by ear".

Advancing initial timing too much will cause the engine to kick against the starter, especially when starting a hot engine. It may also cause detonation at higher engine loading.
