RE: More questions on timing...not answered below
By Gerry Proctor - 06/03/2004 7:09:19 AM; IP 207.133.188.254
How much resistance the starter has to overcome to get the crank rotating for the engine to fire depends on a number of things but most of all the cranking cylinder pressure.

Assuming that your starter, solenoid, cables, and battery are in good shape you probably wouldn't have any difficulty up to 150psi or so. How much harder the engine is to crank when it's hot depends on how the heat soak affects the efficiency of the components and whether you're dealing with fuel percolation or not.

Before the advent of electronic ignition controls we used to interrupt the ignition circuit during cranking and once the engine was up to cranking speed, throw the ignition switch to fire.

But why are you using so much initial advance? Are you trying to run without the vacuum advance?
This thread, so far...
