hey, I havent used my T-maxx in a while so I try to run it today and it starts up and was idiling kinda weird and then as soon as I tap the throttle it instantly cuts out. Its a TRX 2.5. What does this mean and how do i fix it? Thanks
 
Was there old fuel left in the tank? If so, dump it, flush it out with some fresh fuel, replace the glow plug and try again. If you still have the same problem, get back to us.
 
no it was new fuel mixed with some not too old that was left in refuel bottle..I didnt replace the glow plug but i took it out and tested it with the easy start and it glowed red hot
 
If the car ran well when you used it last, the fuel would be my first suspect. How and where the extra fuel was stored might also be the problem.
Flush out the system, start with fresh fuel that was in a sealed container and see if it will start.
If not, I'll give you some carb settings that you will need to tweak it till it runs.
 
well....it didnt run real well...it would cut out on acceleration (i know it means it lean) and i couldnt ever get it to run real good
 
Okay, here you go. Take your time. Very small adjustments each time. You'll actually see and hear it getting better as it gets closer to its' happy spot.

Put the nose of the truck against something firm so it can't get away from you. If you have an EZ start, keep it running while moving your LSN one way or the other till it starts to run.
Adjust your LSN and idle screw till it idles well and will run up to half throttle. (get it to running temp before you finalize any settings) When it idles properly, throttle it to half and see if it stalls or bogs down. If it stalls, it's too lean. If it bogs, it's too rich.
Now go to full throttle. This is when you adjust your HSN. Same thing. If it bogs, it's too rich, stalls, it's too lean.
When it seems to be running good, pinch the fuel line. It should speed up slightly and then stall within 3 - 4 seconds. If it stops quickly, your LSN is too lean. If it takes longer, the LSN is too rich.
Drive it for a while and then take a temp check to make sure it's at the proper temp. If it's too hot, richen the HSN.
You will have to make small adjustments on the HSN almost daily to compensate for outside temperature and humidity.

By the way, the factory settings are for break in, or a starting point if you really messed things up. Once an engine is broken in, don't expect it to run right by going to those settings.
