Hello from a new member in Mi. The swap of 301aqs into 310a spot requires the replacement of everything from the bearing plate out (bearing plate, flywheel,screen and blower housing) in order for the swap to fit into the narrow frame. As for the starter/generator, the bracket will bolt right up to the mounting holes for the later model starter. Remove the electric PTO and replace with the PTO setup off the 122 motor and the original start/gen belt will work fine. At least it did for me! I also did the reverse in my 169 to try to get it to start better in the cold Mi. winters.
