Engine upgrade
 

I'm thinking of upgrading my 86 Marathon Gas, replacing the Robin with a newer larger engine, (more power is GOOD!!!!) probably another 2 stroke out of a snow machine. Anybody know what will fit and what modifications will need to be done to get it to work in my cart???? Also will it run backwrds like the Robin or will I need to change out the rear end???

Thanks

also say goodbye to reverse unless you want to change the rear to a newer one , good luck
