Yeah, I can't even guarantee the LM1 is working exactly right. I have 20 degrees of mechanical advance set to 38 max all in early. I am still rich on the mains too. I am running 160 main jets so maybe I could try the 65 idles with 155 mains. This acceleration stumble is definitely late in progression circuit. I don't have the stumble at higher RPMs. Another way to attack the problem could be to bump the idle holder to 100 from 90 with the 65's. The acceleration circuit might not be as affected by the holder as it is the jet.

Any thoughts?
