ok i need some serious tuning help. my buggy ran great untill i switched fuel and know i switched back to the original odonells......and it runs like shit.

If I turn a needle it doesnt change the engine at all. the needles have to be off like crazy.

I had it pig rich and then i leaned it out by 1/8 turns and finally i prolly turned the high speed nedle a full turn and its really slow. I temped the motor at240 and it was oging like 15-20 MPH and its just really hard to tune.

I need help please.

does anyone know what the factory settings are for the ofna picco .21 motor with an O.s. carb?
