Default tuning OS Speed

as the title says... i have a speed with about 6 to 7 gallons of fuel through
engine ran great till about 5 to 6 tanks ago... cant tune the bottom end.. i have tryed new fuel. resealed the carb,the back plate, replaced the fuel tank, fuel line, and exhaust pipe. the engine has good pinch and does not die when at temp no slop in the conecting rod and or the pistion. i regulary replace the glow plug cause i dont want it to fail during a race, is this thing just shot or what.

well my speed ran awesome for the first 4 gal. then it kinda did the same thing. Depending on how you broke the motor in as well. If it still has some pinch that is good. The middle needle(fuel mixture) could be affecting as well... I just toasted mine up at the pro series in wolcott, ct. They do not like dirt in the motor....lol

I assume you tried a new P3 glowplug though?
