Looking for a manual for above Rotax motor. It is in a ski doo snowmobile. I can't find one that shows me all the information I need. Any help would be great.

Thanks
Bruce

I would suggest you poke around in some of the vintage sled sites for information. It is a basic point ignition sytem and adjustable diaphragm carburetor. Manuals were hard to find in the 70's. The specs will have to come from another source.
