I think I am building up some carbon on the plug. Just a tad rich. But it likes choke to start, so it isn't the pilot. I think it is the 1mm shim or modest main jet increase causing this. I need to eliminate the cat, so maybe will leave it slightly rich for now. Runs great throughout throttle/rpm range. Here is a pic from this morning's activities. I set the feeler gauge in place, snugged up the adjustment, pulled the gauge out, and found that it is ONLY ~1/8th turn to 0.002" OK fine. I think that you can set these things by 1/8th turn instead of dealing with the deepset gap in these heads with limited access ports! I set intake 0.002" and exhaust 0.0025". The Intake valve is harder to access, but I found my previous settings held stable. Nice motor |
