Re: Hot Engine Won't Start

Something else that will slow down a starter is an overly advanced ignition system.

There is a reason that you have an initial setting, a vacuum advance that comes in immediately, and a mechanical system that works as the engine revs up to a speed that more matches the speed of the burning gas.

So if either advance system is stuck (or the initial is too much) the easy to fire warm fuel mixture is burning and pushing against the pistons as they come up instead of waiting until they are near TDC and slowing down the starter.

An easy way to check this is when it's hot and turning slowly, pull the coil wire off the distributor and see if it cranks at normal speed.
