Guys, I got a engine on trade and can't seem to ID the maker. It has M 61 on the crankcase side (Drvers side) on what appears to be a aluminum stick on tab. Made in Taiwan on rear crankcase cover. Ball bearing, never run as far as I can tell. No muffler. It looks identical to my new OS 91FX. Even the muffler off the 91 will fit it. May be able to get a picture of it. Got any ideas?

Sounds like it might be a Megatech engine.

I went to website and it does look very close but it appears the Megatech has a dark anodized head and ABC. I think this engine has a ring if my sight is not failiung me.

Could be a helicopter version, or just an older version of the airplane engine.
