Centering the Carb Butterfly? This is what you're supposed to do right? I had it set so that when you looked into the carb, with the choke fully open, the butterfly was perfectly matched with the choke. The engine is a used G62 and I went out to run see what kind of numbers it would do. Wasn't even close to what it should be so I took the end point adjustment up with the engine running. At 100 points the butterfly was fully open. I took it to 150, which is over rotated past center, and it gained about 350 RPM!

I haven't had a chance to take the cowl off and check it out yet, but I'm heading out to the garage in a little bit. I'm going to see if I can lengthen the pushrod and see if I can get any more out of it.
