Hey all,
I recently changed out my Main jets from the Stock USA 122.5 to 142.5 and the pilots from 37.5 to a .40. I did drill the two holes on either side of the slide needle diaphragm with a 3/52 drill bit. I've got very nice throttle response with the air mixture screws turned out 3x. However, when the throttle is 3/4 the way pulled it seems to bog a little. Any suggestions?
