I had an issue once I added an exhaust system to my camaro only to find out I had the wrong plug for the merlin head. I know it's a long shot but also check the pill in the rev limiter.

to much fuel bleeding into the engine while sitting for extended time?? Takes a good hard pass to clean it out/???

no clue just a thought

I always shut off the fuel pump and clear the carb after each race. This makes sure I have no fuel left in the carb as I was having the same problem in my bracket car. Seemed to fix the problem

If car is sitting in a way that the carb is below the tank or cell with no shut on fuel line; the gas will bleed into the engine. ???

Pat Collins ( TechWest Racing Services ) is right on regarding loose or oxidized connections to the coil / MSD ; been there done that . It may not be the problem in this case , but is good advice for any racer.
