Oddball engine of the day

This was given to me today. The lady I got it from had no idea what it came from, but it looked good hanging from the rafters in her shop and I had to have it. Any ideas?




Carb is Tillotson model YC3A
Spark plug- Champion 6COM62

Measures about 20" plug to plug

 

Cool lookin mini-mill if ya ask me.

 

its a 2 stroke right?

 

It was hanging from the rafters(hung up by her husband 20+ yrs ago) carb down, yellow wires supporting it. The distributor has an alligator clip type adjustor for moving the timing(about 20 degrees overall).

 

That one and one more will make two of those that I've seen. Looks like just the excuse you need to build some little kid his or her first hot rod.

 

i mess on alotta small engines and havent seen a 2stroke opposed v-twin pm me if you figure it out im curious, and the exhausts w.t.h. is with that?

 

Im probably wrong, but the first thing I thought of is an old wash machine engine.

 

I have a bunch of them. Looks like a Mccullough

They're from old drone airplanes. You know, the ones they used to practice shooting down.

 

I could think of more than a few things that could be used for, that's for sure!
Any plans for it? Restore the engine, or make a project of some sort, or?

 

thats awsome

 

Thats right , it's a military drone motor .
They made them in single cylinder also .
I think they were also used in unmanned , spy planes .
Very cool , old motors .

 

Check your old hot rod magazines... I've seen the bigger four cylinder versions in small front engine dragsters.

 

You used to be able to go out in the desert near some of the military practice ranges and pick these thing up out of the sand. I'm sure there's still a lot of them laying out there covered with sand. Jonnycola is correct, they were built by McCullough, of chain saw fame.

Had to edit, 'cause I meant you could pick up the engines. The airframes of the drones were usually pretty trashed.

 

Wow that is super cool...bet most had a very short life span....

 

McCullough. Yes, two-stroke. Quite common back in the 60s to power gyrocopters. You know, those sorta helicopter looking things that look a bit weird, but reportedly flew nicely. Don't know much about them, but that's what it is.

 

Righter 2-GS-17 / O-15-1, 1941

Down at the bottom of the page is the engine.

 

Just holding onto it for now. But if I could get a distributor cap for it....

 

Actually, they got their panties in quite a bunch if you shot at the drone, you were suppose to shoot at the target they pulled. Ask me how I know

 

I know these engines make great garage art. But are they worth anything?

 

Cool find. Mini boxers.

 

Aeronca in the 30s built a four-stroke engine very similar to that to power their little C3 single place high wing tail-dragger...

 

I could see that powering a mini-airboat in a fun piece for you and the kids.
Not too fast but loud and fun.

 

thats really cool, i didnt know they had drones back in the day, thought it was a ultra light engine at first. my dad used to race desert and the only thing his seen sticking out of the dirt was bombs.

 

A mini sprint car go kart with that engine in front would be really kick ass...It's air-cooled so it'd be relatively easy...I bet there's a compatible dist cap out there from something. Cool find!

 

The carburetor was sold by Tillotson to the Righter Company for use, as stated above, on a "target" aircraft. Sale date was 1943. The pictures are upside down. The carburetor is an updraft, which hangs under the manifold, not on top.

Jon.

 

Any recommendations on where to find a dist cap or propeller? I'd just like to make it look more complete for now. Any ideas on value on this engine?
