Hey everyone, Kinda new to these go engines, first

, had it pinched by Rex and got it put in the buggy. Fired it up for the first time to night and started to tune. Well, I set the high side, bench tune, and move on to the low side. If I set the engine to idle fair then nail it, it is WAY fat till it cleans out, now I start leaning it on the low side and the thing starts doing the really fast idle like its lean, but it had good throttle responce. tryed to back the idle screw out but she just won't idle down. So it's back and forth. How many turns out from closed is a good general starting point. Oh yeah, this is a 7 port bout 75*-80* low humidity.
Thanks everyone,
Mike
