Hi, I'm running a traxxas 3.3 engine. I've read the "tuning bible" and a couple of others also and they talk about needle balance. I can't help but believe that I'm close to a good tune but it still gets hot...takes about 3 or 4 minutes or quicker if ya don't give it a rest.
I've sealed the motor using the copper coat sealer and that made all the difference in the world as far as a consistant idle. The little truck seems to run and idle good. I have plenty of smoke at wot and when at idle, the engine will begin to cool down.
Does anyone have any more ideas? There is no binding anywhere that I can see.
Thanks
