    So when it dies, does it restart right away, or do you have to let it set and cool off. If you have to let it cool off, your piston and sleeve may be worn out. If it just dies when you give full throttle and the restarts, then it is a tuning issue

    Hm not sure what the temp is but when it dies it starts again. But this engine is always hard to start and every time i must priming it 2 minutes and then the fuel runs slowly to carburator and piston/sleeve looks god and have running about 1-1/2 litres optimix 20 rtr nitrofuel and the highspeed needle i have set is 4-5turns out

    You can never tune by the amount of turns, no 2 carbs are identicle and within reason no 2 engines are.... Try tuning with this guide I wrote up and see what you think... https://forums.traxxas.com/showthrea...ul-Tuning-tips
