It would stall from driver error (flip it over) do you happen to know how fast a roto starter spins (the air gun spins at 10,000 rpm)?
It ran great until the rear diff. went and it went front wheel drive. It was repaired by a dealer but the adjusting bolt in the transfer case on the out side of it is missing. it runs on white lightning brand fuel with an plug that is a little bit taller than a OS-a3(don't know specifics) H.B. doesnt have instructions online.
