Stroker engine "diesels" after I shut it down

Timing should be less then 15 degrees advanced at Idle. More will cause a problem.

What kind of problem will it cause?? I run mine at 32 degrees locked at the advice of Brian at Indio Motor Machines and my car starts, runs, and shuts down fine. No problems at all.

I also run my secondaries cracked open allowing me to turn the idle speed down so the primary transfer slots are not over exposed. This was also at the advice of Brian. Car runs great.

Like others have said he should try more initial timing so the idle screw on the carb can be turned down.
