well i got a snowmobile engine for christmas. i was gonna put it on this vehicle, but when i ratchet strapped it to the scooter and started it the scooter vibrated across the driveway. i had this lil 2 hp briggs that i did a "restoration" on (added a decal and jb welded the fuel tank). anyway the drive is self explanitory. im machining a pully to fit the rear axle, and then i just build a belt guard, wiring, foot pegs, heat shields and an exhaust system... now i just need a good name for it
