I have a mgt 4.6 with the thunder tiger .28 motor. Just broke it in and it seems to be running pretty slow. I leaned out the high end needle a quarter turn from factory setting and the low eend needle I leaned not even and eight of a turn. Smokes pretty good but seems like it's sluggish and most of the time won't even shift into 2nd gear. Truck is brand new.....does anyone know what would be a good setting for my engine?

Take it slowly while you are breaking in the engine, at least for the first dozen tanks or so. When tuning, let it get up to temperature before fiddling with the needles. If it will idle and accelerate without dying, your low end shouldn't be TOO far off, so leave it alone until you get the high speed closer to dialed in. Right, so once up to temperature, make some passes, letting it come up to full throttle. If after a few passes it doesn't seem to be picking up RPM, bring it in and lean out the high speed 1/8th turn. Make a few more passes, and if necessary keep repeating the process. You shouldn't need to lean out to less than two turns out on the needle, and keep alert that there is always some smoke. If it seems to be dying off at full throttle, you've leaned it too much and should richen up the needle immediately. Your shift point may also need adjustment, but I think running over-rich is the main cause of the sluggishness you are describing.

Yea, slowly keep leaning it out, till the engine is fully broken in, and the RPM's will keep coming up, and it will shift. Don't start messing with the transmission yet.

As long as your not getting excessive smoke at idle and such you probably aren't too rich. Take a look at this guide. It should help you get the basics of tuning down. http://www.rchobbies.org/cars_eng-tuning.htm

Hello everyone, new to this thread, just bought the MGT 4.6 from tower and will be gettin next week. I have been racin nitro stadium trucks for the last few years and wanted something to bash around with with my son. I have been thru a few breakins over the years and know the procedures pretty well. Is there anything you guys can think of that I should know about the MGT before breakin or any tips? This will be my first nitro mt and not real familure with them. Thanks.

Oh, how ya doin docphysics

The manual comes with detailed instructions for engine break in. That's what I did.

I am doing well.

Almost forgot a new pipe would help with noise and performance.
Lst2 pipe can be had cheap.
But dont ask me how to put it on.

thats usually asign that the slipper is to loose, i reckon your slipper pegs have worn down to far and the plates are just pinching on the spur, so it slips alot and creates heat which melts the spur away around the slipper pegs
