Snowmobiles use that engine

The max i just bought the guy said it had a rotax in it also. he said it came from the factory. He said i could get parts from an airplane store because they use that engine in hang gliders..

It may not be common in Florida but those engines are common in snowmobiles making it very easy to find parts if and when needed.

Is yours a two cycle motor?

Yes, its a 2 cycle. Anyone know the fuel oil mix ratio?

You best bet is to contact a BRP snowmobile dealer

The Rotex engines I work with in Ski-doos have oil injection so I am not 100% sure what the perfect mix is. The older sleds had a very rich oil mixture but I have been told that with new 2cycle oils it does not need to be as rich. I have seen the mixture as rich as 20:1 on a Rotex but most are around 40:1 or 50:1. If you go to rich you may just fowl the plugs and possibly gum up the carb. No big deal both can be easily cleaned. To lean of a mixture could cause problems far beyond cleaning.

I have also seen an 8hp JLO engine in a Jiger take 16:1 oil mix but I usually do not see it that high not even my weed trimmer or chain saws take that rich of a mixture.

I would say 32:1 would be safe with quality two cycle oil but you may want to get in touch with a BRP dealer. This will not be the same engine as the Sea-doos they are lake/ocean water cooled.
