I can't get my weber to stop dieseling. I have retarding to timing to just above where it starts to run bad, and thought that would help but it has not. Has anyone else encountered this problem?

I remember having this problem when I installed my weber, I think it turned out to be the idle mixture screw.

Retarding timing excessively increases temps possibly making dieseling more likely.

Idle speed too high will too.

If it still diesels w/correct timing,idle speed and idle mixture adjustment,try one of these:

I dropped my idle, and made some mixture screw adjustments, and will report back. Thanks for the link as well. I may get a solenoid for good measure.

Run-on eliminated, although it smells rich. Am going to lean it out a tad to try and find the sweet spot. If only I had a timing strobe.
