Here's some pics and a sample of articles on the introduction of the KMS-4 from a 1975 issue of Chainsaw Age Magazine.
This was also the year Fichtel Sachs bought out the 60% majority share of Dolmar in January 1975.

The Wankel saw sold well in the U.K. but was plagued with overheating issues, was also hard on fuel.
Back around 1980 my Jonsereds dealer also sold Sachs Dolmar , he had a KMS-4 sitting on display for about 5 years. It was never used and he offered to sell it to me for $500. Too bad I didn't take him up on it. Would be worth a pretty penny today.

I was told these were bought by the forest service and they started a fire using them.  That was part of the down fall for this saw. True or not no clue.

Nice info Willard, Thanks for sharing it with us.

I've seen some pretty impressive hot saws built out of a Wankel engine. Only trouble is most shows won't recognize them as a one cylinder engine.
Hard to believe they put them in snowmobiles and such over 40 years ago.

A friend of mine had a 1970 or so Arctic Cat with the 303 cc. Sachs Wankel in it.  Very smooth running, and had a unique idle sound to it.

Damn that looks complicated!  I always thought it was a great application for a rotary. 

A single rotor is equivalent to a 3 cylinder 4-stroke.
