If the engine is a Traxxas it will have TRX 3.3 on the side of the engine block. All of the manuals are available online at www.traxxas.com.

sounds like engine is running to lean. count how many times the high end needle is out. will have to retune engine before piston seizes completly up.

i'm new to revos two but i just bought a couple and had the same problem with one of them, make sure your glow plug is ok or just replace it and adjust your high speed needle, i'm in oregon i had to richen mine about 1/4 turn. i also noticed both of the models i got were set differently from the factory. there's info on traxxas website on where the factory needle settings should be.

try checking the auxillary fans if its working, replace it if its not. hope this helps

you might need to reset the opti drive. turn the power on with the engine still off and hold down the optidrive button for 5 sec. see it that works.
