Old 2 cycle cart big block and reverse.

I may have a idea that will take work but it would be cheaper than buying a new rear end.
Utilize the old starter generator from a 2 cycle ezgo to run backwards, hook it up to the clutch and shut the engine off and flip the switch, in theory the starter should run the cart very slowly in reverse. And when you are done going backwards flip the switch off. Maybe this works idk haven't tried just a idea I though of.
