could you give a little more info on what it is doing, for example does it idle, does it die when you give it gas just a little more info will be help full.

I can get it to run but when I go full throttle it screams like it should be flying while its actually only going about ten. It is a traxxas Pro .15. Other times when I play with the settings it will idle but boggs and stallls as soon as I touch the throttle.

it might not be the tuning it could be the clutches i would check those, and it could be rich just turn the high speed needle a little at a time till it get were it has power but still blows good smoke.

its safe to say that if you are expelling unburnt fuel out the exhaust, one way or another you are running WAY rich.

If you are running rich the motor will die sometime's because there is so much fuel going in.

I have saw a lot of poeple get confused on the high speed needle on how to rich and how to lean the motor.

For rich turn left / Lean turn right.

Most people i see do it the other way around.

If you dont have a temp gun i recomend you buy one.
Go from $20 bucks up $ 200 bucks lol.
You can also buy a onboard temp which is what i use and love it

Here are some video's below that may help you out.

Well last night I rebuilt the trans and figured out why it wasnt going anywhere. The diff was wasted. So now that all of the gears have been replaced I can now start to figure out why it doesnt run.. The motor has compression but I cant get it to idle. I adjust the idle speed screw to no avail. The bottom line is I have no idea what Im doing. Anyone that Is willing to come help me tune it will be compensated for there time. I live in Monroe Twp NJ.........
