I am trying to find out what type of engine this is. I think it was used on a drone. The only part I can identify is the carb which is a Walbro SDC-80.
The cylinder has 121/1c on the back and a symbol that the looks like an S with a K in the middle. The magneto (I think) has SEM Sweden stamped on it. Any ideas?
