I am modeling a standard, classical, distibutor ignition system, like one in a Ford 289, circa-1967, and I can't figure out why everyone I talk to tells me that when I start cranking the engine on startup I want a small amount of static advance. It seems to me that if the engine is not turning and the spark happens at, say, 6 degrees BTDC, the piston will try to push the crank backwards. Maybe the starter-motor is strong enough to force a burning cylinder-load of fuel past TDC?
Thank you very much for any insight you can offer.
have the same problem?
