Vintage Ski doo 1976 Elan 250 Motor I don’t know much about this motor I did not try to start it has compression not sure on spark I would guess that the points may need to be adjusted  the compression release is there but I could not make it work I think its the cable I do have air duct for it in another Listing I didn’t think it would ship with motor and live you get what you see make sure you ask any question that you may have I will try answer
