What engine is this?
 

A mate of mine just brought a new trainer but it came with very little in the way of instructions for the engine so we dont even know what make it is.
It has an M 46 sticker on its side and has a round cylinder head which is painted black on top. I know its not an OS a Super Tigre or a Thunder Tiger, and its obviously a .46 size.
The plane itself was your typical 40 size trainer called a "World Star".

Does anyone know what make this engine is?

Thanks,

Troy.

without pics its hard?

but my take on the subject with a quick think (just got up ya know :)) sounds like a MAC, i think they were soviet built, is the casing rough cast?..

you got any pics of this engine???

best wait for the engine guys to get in here as im still rubbing my eyes (DAMN RCU ;))

It is probably the Megatech m-46.

RE: What engine is this?
 

Yes thats it. The Megatech M-46.

Do they have a website? Also we seem to be having fuel leakage problems around the cylinder head. Does this have a gasket? The cylinder head has been removed and Im wondering if a gasket has fallen off or something?

Megatech's website is:

www.megatech.com

But there isn't much info there.
As to the leak, there shouldn't be a gasket at the head. You are more likely to find a metal shim between the head and the crankcase. The shim is to control compression, if it's even installed. The glow plug does have a metal seal and if this is missing, it could lead to leaks. How does compression feel?
