ok i rebuild my blaster, all new seals, replaced crank seals, and cleaned everything and it had no power. 4cfed told me to get a smaller jet, so i put in a 280 and it gained SOME power back. once the rpms r up they stay up for a few seconds and it loses the power band. also its smokeing EXTREAMLY bad out of the exhaust and smells like engine oil. not 2stroke oil. and i replaced the crank seals so i dont know what the f*ck is going on.X(
