Can anyone identify this engine? It has an ASP muffler bolted on it but that brand marking on the engine is not ASP?

I thought maybe MOKI or Mark. Or even an old Magnum. But I can’t find any of their engines branded like this. Nor did I find a 12CC in their engines.
As you can see it is also marked with 12 which I expect is 12CC. Physical size is correct for that. It must be a long stroke or at least has a long piston rod in it???






Maybe the carb markings can help???

The logo on the carburettor is that of HB: Helmut Bernhardt, a german manufacturer now defunct, that used to build Veco-based (I think they started out under Veco license even) engines under its own brandname.
The thing is, I have in all these years never seen a metal carburettor with the HB logo on it. HB mostly used Perry carbs, and a few own-design carbs for heli's and buggy engines. Those "own" carbs were twin needle but cosmetically pretty strongly resembled the Perry looks.

I cannot bring home the engine, but it does not look like anything HB ever made.
The pics are too vague for me to properly make out the shields/markings on the engine transfer port

Thanks for the input Brutus,
Here is a better picture of the "LOGO/NAMEPLATE"

That logo is totally unknown to me unfortunately.

I searched that picture using "GOOGLE".
From the results, it looks like that is an MVVS engine. Several on EBAY with that branding

thanks for looking and the input

That could be VERY possible.
AFAIK Helmut Bernhard ceased production of model engines somewhere in the '80's after the company founder, who was an avid RC modeller, died in an accident.
The company still exists but has no RC related production in any way, so IF your engine once came with that carb, it's an oldie.

MVVS were and are mechanically sound and well made engines.

here is some other information I ran across in the case anybody else is looking for more info on this engine.
I learned the engine is actually 12.7CC (.77 ci) even though it is stamped with 12.

Picture attached is from this web site. I have no idea if this is an active/current website or an old website still hanging out???
Old engine models bazaar
MVVS .77 RC NIB - Glow engines


MVVS .77 RC NIB - Glow engines
As you can see this one has a different carburetor on it versus the one I have.
I have no way of knowing if the Carburetor on mine was something that was added after the fact or if it actually came with it new?

Given that Helmut Bernhardt ceased production before the Iron Curtain came down, and MVVS back then was produced behind that curtain, I would guess it to be a later modification.

But that is just what it is, a guess.

Engine is a Check manufactured "MVVS" 12cc engine, ABC, With ballbearings. Carb is a German HB (Helmut Bernhardt) with 13mm neck .Silencer might to be an British "Irvine" as Irvine has narrow silencer fittings compared to OS and ASP.. Both HB and MVVS stopped producing glow engines many years ago ...sadly! But I have lots of spares for MVVS engines if you are interested and some engines too.

HB made many parts for K&B as well. Perhaps the other way round at times too.
MECOA Engines makes and stocks HB.

The Czech made MZ are impressive engines.
