My JATO does not run very long it will only start right up when its cold it does not even burn up one tank of fuel. i try to start it up again it doesnt want to i dont know what to do ive only ran about 1 and 1/2 gallons of fuel

Have you checked your temperatures when running? How well does it run when cold and does it start easy when cold. Either you need to retune or the motor may need rebuilt.

I have had the same problem with 2 engines of mine. Both needed to be rebuilt. My brother and I just screwed with his 2.5 rustler for a full day because it was doing the same thing, a trip to the hobby shop for the 3.3 fixed the whole thing.
