Hi Gents,
I need your assistance. I have an unknown 2 stroke engine. The only marks on the engine are: one one side of the case is the letter M with a line above it, on the other side there is a number 12, on the bottom side of one mounting lug there is a letter S, on the other lug there is the number 70. Other than a grey/black cylinder head, those are the only identifying marks. It looks to be larger than a 60 size and perhaps about the size of a 90. Any ideas?

Photos may help.

Need pitchers bad. Does the construction resemble either of these. One is a MOKI .61 LS and the other a MOKI .51 RC. The .51 has an M and a 5 on it.

Regarding the "unknown engine, I will try to get some pictures for the next post. It does not look like the engines in the photos. In the meantime, the engine is a one piece case and the exterior is not smooth like most engines. It has a "sandpaper finish." In addition, the needle valve has a built in flexible spring. It is not an air bleed carburetor. Now you have exhausted my knowledge of the engine.
Thanks for your replies.

That finish almost sounds MVVS like, this is an MVVS .91 that has the finish you describe. Sorry to be wearin ya out.
