Fuel spitting out my muffler

[Big J]

I am total newb to Nitro RC. I had a hobby shop tuned my T-Maxx 2.5 for me and it was working fine. But my buddy started messing with my truck and now when I run my truck I am getting alot of unburned fuel coming out of the exhaust. Any ideas on how I could fix this? My nearest hobby store is is over a hour drive away. So If I could do this myself that would be great.

I would go outside tomorrow and run it and re-tune it yourself. You'll have to do that each time you run it anyway for it to run best.
It sounds like its too rich, but how does it run now compared to before your friend messed with it? Do you know if he touched the HSN, LSN, or idle, or all of them?

I want to say he touched the screw/knob next to the air filter. It ran perfect before, It stayed on at idle, no fuel out of the muffler and a good trail of smoke when I ran it.

turn your HSN high speed needle AKA "knob next your air filter turn it in untill it run correct again"

Do little adjustments. a little turn to "the knob by the air filter" at a time

make sure to turn it in NOT OUT

Is it spitting fuel at idle and low speed? If so, you'll need to lean the LSN in small increments till you get a good take off.
