Things are really shaping up. I have gotten very close to having a happy engine with Weber's. I had a lean stumble between 2000 and 3000 rpms. I went from a 60 to a 65 idle jet. I seemed to run great, no stumble and good acceleration but my LM1 was reading really rich like 10-10.5 to 1 a/f. I went back to the 60 and the ratio climbed to 12.5 to one at an easy cruise which was good. When I hit the gas to check acceleration, I'm back to the lean spike/stumble. I have a 40 exhaust jet in the bowls now. Should I just put the 65 back in and run rich or should I switch to a 00 bypass. I don't have any 00 exhaust jets so I need to order them if you think that is the issue.

My main jets are 160's in f7 tubes
