Thanks guys. The engine I am working on now is a GT25 I got from Scott (poco242). It has no carb or exhaust. Took the intake off and the ports look fairly large. I do not know if he changes the timing or what. His engines do run real good when he gets them ready. It looks like the carb adapter has to be redone or replaced. I am kinda looking what may fit the bolt pattern. Maybe the carb off my G38 will work. Well time will tell. Got to go work on ny nephews cycle now. Capt,n
