The KMS4 entered the USA in 1975, and was not sold here for very long.
It uses a standard Tillotson HS carburetor. HS kits are easily available.
No, as I understand it, the saws were never recalled. According to legend, sales were stopped short in the USA because the heat of the rotary engine causes the muffler to grow cherry red after a period of use.
After I heard this legend, I ran mine in the dark one evening. The results were amazing. Not to be tried near dried grass or leaves; as you may find when working in the woods!
Legend also claims they were very smooth, but also very thirsty saws. Instant acceleration, typical of the rotary engine.
Rare, they are difficult to find, but can be found.
I do have sales literature, operators manual, and parts list for this saw if interested. I also have the workshop manual, but it is in German.
