you need way more initial timing...more like 16* not 6*... What jets/PV/squirtter/springs? Unhook the vac advance, set the initial at 16* total at 38* at 2200rpm. Then turn your mixture screws all the way in, then back out 1/2 turn and adjust for best vaccum. That cam is probably going to like more stall and gear. I don't have a idle solenoid and my junk starts right up.
