Answer this question…there isn't a specific mix but you don't want to much because it can cause the spark plugs to foul out. if you do put any in put a little bit .also always run your snowmobiles on premium fuel
their really is not a specific fuel octane mix. if you just run premium in it, it will be fine, but if you do put octane in, just put a little bit in it. because it could make your fuel too rich and foul out your spark plugs.
Yes it does, the size is 256*38 i think
they have oil injection. but if your are not using it, 40:1 is a good ratio.
most likely a crank seal is leaking, or carb boots. have a shop test the crankcase for leaks
