RE: Centering the Carb Butterfly?
Nope, no dice with that one. Remember, I just bought this engine. The only way to start a "new to me" engine is to start it rich and lean it out from there. I leaned it to peak and back it off a little. Then started playing with the EPA.
Just got back from the garage and pulled the cowl. It's definitley past center now. I adjusted the pushrod so that I now have maximum travel at full throttle-the bellcrank is hitting the mechanical advance. This is way past center. I'll fire it up and see if I gain anymore RPM. I tried to get some pics but the butterfly is in too far.
