Please help me identify this engine
 

I got an engine with a big "S" on the left side that I can't identify. I bet it's a nitro engine.
Here's the observed specs:
head diameter: 33mm
Height from base of mount point to top of head: 60mm
Total height: 75mm
Muffler screws seperation distance from center-to-center: 35mm
Carb inlet diameter: 9mm ID, 11mm OD
total shaft length: 83mm

Here's a pic of it next to a gms .25

As near as I can tell, Saito only does 4-strokers. I think it's a 2-stroker, so I don't think it's a saito.

Looks like an old Sanye clone, if so it's not a nitro engine you use FAI fuel on these, maybe 5%.

Is there anything stamped on the carb? Could be a Sanye or another OS clone. Looks kinda like a BX-1 (1.08 cid).

There's nothing stamped anywhere that helps identify it, except maybe "Made in Taiwan" with a "3" stamped under it on the backplate.
It's a TINY engine. My GMS .25 is slightly larger.
As for this thing probably being an older engine: I doubt it since it still has the rubber stopper on the shaft that most brand-new engines have. Atleast this engine has most likely never been used.

So uhhh, what happened to the GMS? I see a little piece of plastic where the motor mount should be[X(].

RE: Please help me identify this engine
 

That GMS was involved in a minor crash with a c-160 that went too slow during final.
I found out what the stupid thing is. It's a SKYWARD MODEL ENGINE 28 EP-B ABC. I had to look at my receipts for that info.
Anyone have any idea where to get details for this engine?
Thanx!
