I was trying to dial in my Boss 302 today, and the cam has .639 lift, 296 duration, 260 @ .050. Here is my question, when I try to dial it in, I set the timing to 16 deg BTDC then I can't get it to idle, then I advance the timing and I can get an idle, but then when I adjust the fuel mixture the thing is thumping around so much I can't really identify if I am improving the tune or not. After screwing around with it for a little while it is now blowing smoke out the exhaust and I still can't tell if it is running any better.
Any ideas on how to tune with a large cam? Or do I just keep going on the trial and error method.
Thanks again
