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?
Regards ,
