I got a rush evo, took it to the track for the first time, hit a tractor, broke a few pieces and it was still running strong.
As the night wore on, it got to hot, (330) I put the piston on the down stoke, bottom, replaces the plug, now today, it runs ok, but the top end isnt were it should be. Ive tried tuning the carb to make it run a bit better on top end, but its just off still.
Could the servo for the gas be off a bit? Or could the new glow plug be bad? Any tips I should try?
Thanks for the help...
