Hot restart issues.

Put a kill switch on the car. Crank the engine with it off and then turn the switch on while cranking. That will solve the problem if its a timing advance issue.

To see if it is the timing take off the coil wire when its warmed up and see if it turns easy. If not , You have a starter or tight engine issue. Incorrect ring gap good be your problem if the engine is tight,

Had a small block chevy here that was tight and it broke the ring lands on every piston between the top rings from tight ring gap. For your sake I hope its the starter or timing.
Yeah thanks .. I’m concerned that tight rings is the problem, or maybe the timing. It’s just that he engine is so crisp and responsive that has me thinking is maybe a starter/grounding / batt issue. I will follow your suggestions and see where it leads. Will keep you posted. thanks for the input bud!
