I bought the mixture screw tool. I turned them in all the way, left side was about 6 and a half turns out. Right was about 7 turns out. Got it to idle at 4 and a half turns out. Running AMAZING now. And, when I turn the distributor cap counter clockwise, looking at it from above the engine starts to stall. No pinging. And, correct me if I'm wrong, pinging sounds like beans rattling in a can, right?
