I have a 52 panhead that I just bought. It is stock motor with S&S super e card and auto advance distributor with drag pipes . To get it started I have to give it 4 twists of throttle no enrichment. Starts 1or 2 kicks. I let it warm up and when I roll the throttle I fine till I get around 3,000 rpms then it starts to die and missing badly. I took it around the block and could shift through 1st & 2nd with a light throttle and if I try to go any faster it dies and starts missing and when it’s hot really hard to start. I tried new plugs ac45 gap at 30. Pulled plugs they have like a black soot on them (not wet). Carb has .0295 and 74 main. Checked coil primary ohms 41 and secondary 19,000. The float was a little low but worked freely. I replaced intake manifold o rings and put 3M 88 tape around and reclamped. Put new insulator block between carb and manifold. New gas and cleaned shut off valve. Anybody have any idea what it could be?
Thanks
