    Change the glow plug and reset the needles. Get it fired up and retune. Also sealing the engine will greatly help.

    The idle was the first thing I immediately noticed because the Traxxas carb can't idle properly to save its life. The Losi carb is rock steady once you get the tune dialed in. I like my engines to...

    What he said. You want it running right at 250 and 270 is max. If you're seeing 300 then you're way too lean or you have a bad engine bearing.

    Also, remove the exhaust header and then turn the engine over until you see the piston skirt. If the bottom of the piston is gold instead of silver then you need a piston/sleeve swap.

    What he said. If you run the stock header don't torque it down like a head bolt. Just snug it up so it can flex a little. Torquing it down is what causes them to break because it no longer flexes...

    The only functions the Opti-Drive performs is to make sure you can't shift between forward/reverse while applying power. It has nothing to do with transmission shifting.
