Snowmobile Repair Information
For the last few years I have had quite a few requests for help from snowmobilers trying to diagnose or repair their own sleds. In my early teens I used to strip my sled to the frame every summer and sand and paint it, and I eventually ended up being a mechanic for a few decades.
I still fix my own, but I am a little out of date. The sleds that I know the best are my early and mid-90s Polaris triples. I can usually help people though, and I am always glad to try. We are snowmobilers, we help each other.
The top question by far is about gas and ethanol. Personally I run ethanol free 93 premium in all of my engines. There is an old article below.
The EAA is big on gas quality and are largely responsible for us being able to get premium without the corn squeezins. Many light planes run Bombadier 2 stroke engines on pump gas, and they are pretty serious about their fuel.
Anyway here are the articles..
