    Question Tuning Help...Please...

    My rustler is acting quite strange. At the top end, it wants to be out almost 2.5 turns. I think that's a lot. It seems to get all the top speed with out bogging and has plenty of raw fuel out the muffler (as proven by putting my finger at the end of it). The problem is that it seems to bog out at the bottom. This is also where it gets weird. I try to lean it out (the low speed mixture screw). Gun it...it'll seem to pick up just fine go back to idle...it'll hang out high a bit then settle down. ok...lean it 1/8 of a turn....same deal...lean it again 1/8 turn...gun it, spins up fine...idle returns to nornmal. Then all of a sudden the idle takes off almost as if it were half throttle. I have to crank down on the idle-speed screw just to make it feel 1/4 throttle. If I run it around a bit, it'll start to idle normal, but then the bottom bogs down again. It seems to run the best when it is sucking fumes. Any ideas????

    Now for the deals on what's on the engine:
    MIP 360 Exhaust
    MIP boost bottle
    Motorsaver air filter
    and it's been turboed

    a turbo, holy cow!!! j/k mine is too. well if i remember correctly my low speed needle is at 1 3/4 turns but 1 1/2 is pretty normal and i run 3 1/4 turns to keep things really cool but 2 3/4 gives me amazing power. oh by the way i have a bit more then you, i have a gpm head which adds compression and cooling, so more power and a cooler engine. i still had to richen the needles for the head though, as noted by the 3+ turns.

    hope that helps some.

    later
