idleing issues

[exmark93]

I've been having trouble gettin my tmaxx 3.3 to idle correctly, it will either idle down and stall or take off once i let off the brakes, the idle screw doesn't seem to do anything, from all the way in, to all out, the idle is the same, the only thing that seems to change the idle is the LSN, I've tuned the LSN to where the truck was jumpy and bog free during take off, but its idle was very high, and i can't seem to get this whole idle thing figured out

What I usually do is......first, make sure the gap in your carb is 1mm roughly. Then turn on your radio and truck (without starting it)...and get your throttle servo centered. If its not centered, take the servo horn off and center it. Put all your needles back to factory. Hsn 4 turns out, lsn flush. This should start ya up. Take a few high speed runs, bring it in. If the idle is too high or low, adjust it a bit on your radio. This usually works for me. Hope it does you.
