1990 Evin. 100XP. The idle is a little to high and I want to adjust it down. I have loosened the throttle bracket in the engine and turned the lower of the 2 in and it did come down some but I need it a little more and Im not sure if I continue to turn that lower wheel will it affect the overall performance at top end. At this point Ive turned that lower wheel approx. 7-8 turns. Thanks again for the help.
