Okay.. New pics! I found a few things in the process of popping it off the kart. The bottom of the motor on the drive side says Mac (perhaps Mac Minerelli?), and the front says 330 (but that doesn’t seem to turn up much on ye olde Google). It’s a reed valve motor and the carb is a Tillotson HL-334A.

Drive Side.. Yes it was direct-drive

Intake Side

Exhaust Side


Crack kills :(
