t-maxx won't idle after warm

[acidsnow]

got a 3.3 t-maxx, seems to run ok, idles when I start it, but after a few high speed runs, it seems to always stall, just won't idle when warm. needles are all at stock. the idle just seems to slow down, and stop after I bring it in . . . . . any ideas?

It probably needs leaned out a little and the idle screw adjusted. What's your temps reaching?

If your running all stock settings after break in....your motor will run like garbage. You will need to tune it once the break in process has been completed. Search for tuning guides out here that will help you immensely.

tune your idle screw.Mines it under the hsn(high speed needle)

If you are running "break-in"settings, chances are, your 3.3 is running to rich. Check out the manual below for detailed info about the 3.3.

I have tuned it well, runs great for 10 min, but after that if I slow down engine stalls. I was wondering if my piston sleeve are getting worn. I can turn the fly wheel with little force (with my pinky finger, only a little resistance when piston get to top)

temps reach 300, but usually run in the 270's

as long as I don't take my finger off the throttle, it will keep running

Check for loose head bolts and make sure the engine is completely warmed up before tuning it. After "forcing" my head bolts about 1/4 turn tighter on my 2.5, it was about twice as hard to rotate the flywheel through the pinch. I used a regular allen wrench with some vice grips to get them to move. I don't recommend forcing any bolt to turn, but in this case, it worked. I'm still surprised that I didn't break a head bolt, so try this at your own risk.
