Can anyone identify this engine for me?

 

There are no markings on this engine that I can find.  ....There is the #63638 stamped on a metal tag tied to the engine, but I don't know how relevant that is.

 

The decal on the shroud is unreadable.

 

The engine has exposed valve springs, a cast-iron muffler, uses a 7/8" spark plug, and has a Donaldson air cleaner.

 

Thanks for any help!

Not sure but it looks like a Wisconson. "JMG". Roger.

It looks like someone started w/ a gas tank and then designed an engine to fit around it. :D

 

But seriously, doesn't Wisconsin have a round decal? You may get more info when you clean all the castings. In any case, that is one cool looking engine. I'd like to see it run on a test stand. :thumbs:

I don't know what it is but I think it's incredible that the muffler and air filter is still there. Impressively complete for an engine that old. Are you going to try and run it?

In that first picture, is the flywheel cover solid? Not screen?

The flywheel cover is solid on the outside but if you look close the inside of the shroud has extra holes to allow air in. The cooling fins must be on the inside of the flywheel[s]. 

I've not seen one of those before but the angled head with side sparkplug mount, carb,intake, and exhaust manifold all look like Cushman.  The remnants of the decal look Cushman too. 

 

OH  and the kill switch sticking through the shroud looks very Cushman-ee  as well.

I think we have a winner!

Sadly, I don't have the time to play with it.  ....It is a nice challenge, and it's the kind of work I like to do, but I just don't have the time.

 

The engine is not seized, and will turn by hand.

Briggs?

 

I really don't think so.  .....I've seen pics of most of the old B&S engines, but none looked like this one.

Thanks, Kris!  ....I never would have thought of Cushman, but you're absolutely correct!! 

 

It's been sitting indoors for the past 40 years or so, so it's not in too bad a condition.
