i have a 120V/600W/4.2A gasoline generator. it also has a 12V/8.3 outlet. it's an old mcculloch "power-pac" in great shape, compact but heavy. i'm thinking "120V motor" but that's about as far as i've gotten with this... worksman industrial trike generator & motor in the bed belt-drive to axle i think 4.2A isn't much. is this doable? yeah, but is it worth it?
