Good morning everyone. Hitting the road shortly. Had the Demon out last night, ran shitty still at the 2700-3200 ish range again. I think I am on to something though. I tried leaning the idle mixture screws as the transfer slots are completely covered. Still bad. Tried richening. Way worse. Unplugged the vac advance, leaving the port om carb open. Idle didn't change. 3000 ish much better. So the plan is uncapped the rear carb nipple (both are manifold vacuum) to see if that helps more. If so, then I was pig rich and can add secondary throttle plate air to fix.
