check some of these things:
- check the rings on the carb.
- check for compresion by turning the flywheel, and seeing if it makes a poping noise, if it doesnt, the engine is dead.
- try another glow plug
- has it been sitting around for a while? let it idle for many minutes to de-gum the carb and such.
- take it to your lhs, and have them look at it.
i broke in my 2.5 engine poorly, and it only lived about 2 gallons. did you not break it in too well? and, did you ever run insanely lean, or at a brutal rpm? those sorts of things could have decreased its life. if it is just too much of a hassle, just use the traxxas planamajig and get a new 3.3 for like, 120$ if you trade in the shot engine.
good luck!
