Need help identifying an old Rotax/Mac Minarelli motor

[Caleb Edgar]

I recently inerited this motor from my grandfather. I have tried to identify what it came off of without much luck. I assume that since it has Mac Minarelli badges on it, it should be a kart motor. Thanks in advance!

Caleb it might be best to post your question on the Shifter kart or even the 250 Superkart boards. Even though its not a 250, a lot of 250 drivers are familiar with the older Rotax motors 124/127 etc etc.

Once upon atime,the first motors were rotaty valve,a piston port model was offered also,those models were discontinued,then a reed model ,air cooled model,then water cooled,what you have here is a rotary valve early version, then a reed assy has been fabbed,the rotax cylinder was added(diret bolt on/install),unfortunatly it should be in rotary configuration,really it is now a nice conversation piece,good for parts&keepsakes,could it be made made to run again?welllllllllllllllllllllll?possibly,but which ?Replacement parts are nonn exsistint any more,if you need help let me know,good luck
