repower as in new power head or just another engine??? My only prob with that is it seems that if an engine is taken off a bot for some reason its prolly one just like mine having problems...... scares the hell out of me to buy a used engine..... i cant afford new..... even when a person can start a motor in a shop that doesnt tell ya jack.... my motor starts perfect every time and runs great IN THE DRIVEWAY!!! Lol
