Help Identify this engine
 

I have a large gas engine. Looks like a Zenoah or Quadra, but much larger than a G62. Looks to be twice as big. The only markings I can find on it are, " SEM Sweden" which is on the points cover, and 121/1C cast in the bottom of the cylinder. Can anyone help me identify this?

Thanks
Doug

Probably a Volvo; I can't tell what year.

Does anyone know what CC this would be?

If it looks like it is about twice as big as a G62 than I would think it would be something like a old QUADRA 95 single or something,,,
