I know that demonsizzler says that some bogs cannot be tuned away unless the air door is tight against stop. He was right. Aluminum headed 440 with 250* duration, I had it gapped at .040 according to the rebuild and had to readjust mine tight even after tightening the airdoor to get rid of slight secondary hesitation.. Would like more info also.

I'm not trying to be difficult, it comes naturally....
