BigMatt, check these videos out for tuning. They're done on an HPI Savage, but all engines/carbs tune in the same manner.

You do know where your idle screw, LSN and HSN are, right? I know the manual sucks, so if not, the idle screw is the middle one hidden by the air filter. The HSN is the outside one that sticks up, highly visible. The LSN is at the side of the carb where the throttle arm connects.

If you find that you've ever messed it up to the point it won't start anymore, here are the base settings - LSN should be flush with the collar and the HSN should be backed out 2 1/2 to 3 turns from closed (all the way in, not too tight!) The idle screw should be set so the throttle opening should be about 1mm or 1/16 of an inch. You can see the opening with the air filter off. When you turn it in (clockwise) the idle increases as well as the opening. Obviously the reverse does the opposite. Once your idle is properly set, there should be no need to ever touch that one again. When making idle adjustments with the engine running, ALWAYS have the air filter installed.

Take a look at this. It's from the redcat racing website support link - http://66.226.4.160/tuningyourengine.asp

Good luck! I got my Volcano SV "erupting" off the line... Really though, she's dialed right in. Remember, your LSN is imperative for quick, hesitation free take offs. Once you get that dialed in, move on to the HSN
