Yea Jud it is a great engine. I was having a little problem with my carb tho. It was sticking on me manually giving me a little run-on after I let off the throttle. I put a hair rubberband on, rechecked my linkage, but nothing helped. So I machined down a extra C6 carb to fit the smaller carb hole on the Killer. I will let you know how it works out. Engine did get great milage, I did a 9 min pit on Sunday and my pit man said I still had plenty of fuel left.

P.S. Ditch the 8mm restrictor for a 7mm, big difference in runtime!!!
