well i bought a blaster and i tore the motor apart cause it was smoking pure white so i thought crank seals. i took the cylinder off and its gonna need bored and then i took the clutch cover off and i see a missing clutch spring a screw. and i also found a that one of the gears (right behind the clutch basket) is missing alot of teeth. is my best to buy the parts and rebuild the bottom end my self or my the parts and let a shop rebuild it for me
