Flea market find

Good free flight engine.

That's what, a little over 2 $USD. Nice engine and a great find.

I have it's brother, a mess when I got it. Painted the cylinder with high heat red, same left-over color as on one of my old MG's engines.




They might have rolled off the same assembly line together Lieven.

Time repeats itself.  I had forgotten all about it.  They all run together, I have done several similiar engines.

Edit add.  

Found it, took me awhile after punching in McCoy in the search function.  I paid $11 for it.  You got the better deal.

Oh yes, that undrilled mount!!!! Gotta be worth a million bucks or $2.38 USD.

Nice Score!!!!!!!!!!!!!!!!!!

This problem might give you some confidence that the engine may have never been run, because the insulated plug may have always prevented it from starting. I'm not sure if this is the likely case here, but I know that the first ever engine I bought was an Enya .09 that the original owner "could never get to start". The original Enya plug wasn't working and it turns out that the insulating washer under the top screw-on thimble of the plug was missing, causing the thimble to short out to the body of the plug. A new fibre washer was fitted and the engine never failed me again. Another similar case was an OK Cub .060 I got off eBay quite cheaply. It wouldn't do more than burn off the prime. I eventually discovered that the brass insert for the needle valve had never been drilled to allow metered fuel through. The engine could have never run like that. A replacement tank insert resulted in an instant start. Another OK example (giving rise to the theory that OK Engine had serioius quality control issues) was a new looking .049B which would not run, with the cause being that an unported crankshaft had been fitted from new. May have missed the porting process, or someone fitted a reed valve crank to the FRV engine.
I've heard of other issues such as a baffled piston or a liner assembled the wrong way. Engine never runs, owner gives up on it and eventually moves it on, hopefully to someone clever enough to sort out the problem.

I truly enjoy seeing posts like this. It's a great feeling that your purchase was very reasonable and that it also works. I know you will be able to get this on something unique and it will certainly be cool lofting around. Kim has his old collection of planes and they just keep going and going. Different engines on some of them give them a whole new attitude and experience.

Maybe it’s my eyes, but it appears there is a lot of aluminum residue in that exhaust oil. If so something is amiss.

I am glad you got it running!

Great Post. Like Ken, I really enjoy these posts with old engines, like old engines I havent seen before. One way you can check is to use bearing blue to see if things are touching. Some people use a texta. Doesnt really work with a running engine though and sometimes things only touch when running. That means you need to go looking for little shiny spots on surfaces or like a little scratch mark that isnt from machining. Use a really strong light and magnifying glass, Ive got one of those magnifying lens lights where its all built as one. I have had engines do this and it goes away when the high spots or such are worn down. Not ideal, but at least the engine is running and looks Great!
