No wonder they didnt last long.

That was a neat video! I'm originally from snow country and had never heard of or saw that machine before. Interesting!!

From my research. Looks like the engine is a 820 west bend.

Some guy did one up modified to 940. Think in read, pics, video he went from slow like they were to close to 75 guessing.

Then a stock cylinder.

There was a lot of innovation back in the late '60s, early '70s. Hundreds of manufacturers, and often it was the successful business plan rather than the best innovations which survived. John Deere, Mercury, Evinrude, and Johnson all made sleds. The first two were likely the first liquid cooled. Bolens made a twin track with a sled pulled behind that you sat on. Bombardier and a company going by the name of Raider each manufactured twin tracked machines with a cockpit seating two people side by side, that likely were before their time.

It was like the early days of the automobile. Lots of company start ups, lots of innovation, A couple of things happened in parallel that drove change. In the early days, there were no trails, so snowmobiles had to be light, and float over the snow. Horsepower and handling weren't front and center. Popularity brought groomed trails. Then the horsepower and handling race was on!

Other day digging deeper into the easy start 180 250 stihl to compare.

Figured be a good time to clean the 250 one before in dads hands while in there.

Crap forgot to take some pics of inside difference.

Just in case I forgot here. But is elsewhere too.

Echo 501 etc oring.

The SAE fits best. Just hair better then the 272 one.
