I found this in my "stuff" box.
Bought it around thirty years ago, new in the box, never run.
Anyone know about it?
Made in Denver, Colorado.

I'll also post it the Old Time topic.

  I have one that is new in box that i acquired many years ago. I was under the impression then that it was a reproduction/replica, and the box even looked too modern for it to be a 50's vintage product. I haven't tried to run it  yet.

  Type at you later,

OK, one test!

My expert opinion?   JUNK!

Remember, NEW!

I took it out of the box and cleaned it out.
First thing I noticed: Minimal if any compression. Felt like a worn-out McCoy redhead.
Not being one to quit, I tried an electric starter and was able get it to run - but not more than around two or three minutes. As soon as it stopped, it had ZERO compression.
I used a 9-6 wooden prop and tried 15% and 5% fuel.
Unacceptable results.

Suggestions?

Sell it on eBay for an astronomical price. Include the disclaimer "I found this at a garage sale, have no knowledge of its conditon, and only assume that it's a model airplane engine!"    Steve

Hi, Dave - interesting reply.
Worn out Fox? I've been flying Foxes since 1956 and NEVER worn out a piston/sleeve but I have seen some worn out front bushings - those I can fix.
Piston appears to be cast iron. Definitely ferromagnetic. Flat top with a baffle.
Yep, I tried growing it - accomplished nothing.
Even if I could fit a ring, it would not work - remember, ringed engines have vertical "teeth" in the intake and exhaust ports to capture the ring.
I do have one trick up my sleeve.
I may be able to fit a Fox piston and sleeve with some clever machining.
We'll see!

A few thoughts based on other's comments:

1. Sometimes you can heat a metal and promote grain growth. Think of it as the atoms getting "more organized." The net effect can be that the part grows very slightly. In an old, much heat cycled part, it may not happen. And it needs to get pretty hot. I'd have to look up numbers from a materials book to guess a temperature for each different alloy. Mehanite might be a good material guess for Fox and McCoy stunts. I never found heat growth to be a real cure, but it seemed to help things a few times for me.

2. I don't think I'd try tapping or other displacement methods on a sintered iron piston, which I believe the Mickey Reds had. I suspect they aren't too malleable. (There is such a thing as ductile iron, though....) I have done it on aluminum pistons with mixed results. By the time the piston/liner is wheezing badly, the rest of the engine is usually pretty far gone, too. So even if the P/L fit is improved, the engine still may not show much promise.

3. Sure wish it was still possible to chrome plate old liners to refit the engine. Might make the engine perform better than stock, as well.

4. Good point about hooking the ring on any larger ports. Since a Remco is kinda rare, I obviously didn't know what I was talking about there.

5. As far as not having any worn out Fox Stunt P/L's---I am in awe!  Sometime I should post the  Al Carbone Caper, the story of the Seven Chocolate Foxes....

I doubt you could ever turn a REMCO nto anything useful.  Even if you could fix the zero compression problem, you would still have a second-rate engine.  Any run-of-the-mill OS 40 or 46 would do better, and at a reasonable cost.
