Used Snowmobiles In Michigan

The seller assured me that I rode it was just cold and that the 4 time necessary to warm up before they start really. Once I got home it was still swampy sled so I checked the compresa and 2 cylinders are falling. What can I do?

You're out of luck.Most private sales are just AS-IS, unless you have a written guarantee.

nothing
Whenever someone says something just needs to "warm"
thats a big red flag

appply a sticker to the GMC and request a document from the federal government.

rebuild or take it to the landfill. If you have not written, you can not do anything.

You took his word. He lied. No matter what state you were in.
