Yet another "What are these?" post.

Some of this engine is worth a lot If you want to put them back in working order Take the time to familiarize yourself with this type of engine To do no more damage than good because with certin of this engine the parts are impossible to obtain Before even cleaning, take the right information Someone here could do it for you if you don't believe you can do it without breaking the bank You should try with the two cox .049 engines to adapt them on a plane it is very reliable in a good way to learn After having learned well with the others you could easily restore the .045 car engine With the help of other members their advice will be precious to you take time To ask Somting Seems strange to you just ask
We will be happy to answer you welcome have a good time here the member are very respectful with the others here

Thanks everyone for letting me know. And the warm welcome!

Unfortunately I am not in a position to take on the task of fixing these up.
The parts of these are on the small side of my comfort level.

So I am off to find some value information starting in the "For Sale " section here.

Is it frowned upon to post engines here other than Cox ones?

I have another bag of engines that are a little bigger I think in the similar age range.
They say 15 , 09 etc on them but I don't know if anybody would be interested in them.

If it isn't cool that's fine.

These ones are rough I think.
Only 2 turn, The one in the fox 15x box and the the "McCoy 29" with the red head.
But the one with the red head has a lable saying it has " A loss of compression after starting".

That's a really neat Enya .09 on the right.  Great little engine.  The four at the bottom are all Fox.  Three Rocket .099s, two of which have had their mfuel tanks hacked off, and probably a Fox .07.  Not sure about the one with the blue head.  Still, nice bunch of engines.  Shouldn't have any trouble getting a few $$ for them.

Rod.

Oh, also just noticed, that's probably a carb off an Enya .29 or .35, looking at the square neck.

The blue engine is a O&R .29 with the bullet tank. It dates to 1950. Very anemic engines but neat. This was nearing the end of the line for O&R as glow had just been introduced in 1948 and was dominating quickly. The 3 engines on the bottom with the rear intake is the Fox Rocket .09's. Two have had their crankcases cutoff which seriously detracts their value. The one that's missing it's tank bank has the full case intact but the backplate is missing. That's not a easy part to source. The engines were severely under powered which had Duke practically destroy many of them and the parts for them sat around for nearly 50 years in barrels. The engines are sideport configuration and will run forward or backwards. I like these engines as I use them for free flight models.

The engine on the bottom left is a Fox .10 Hustler. A very improved version over the Fox Rocket .09. It had decent power. Plugs are not so easy to source for these but I see you have a few extras. The Fox .09 plug and .10 plugs interchange even though they have different shapes.

The Redhead Mccoy could possibly be salvageable. They were mass produced and quality control was far from good. It's not surprising it has little to no compression. However, Mccoy used paper fiber gaskets in the head and the base of the cylinder. These could be replaced and you might have a fine running engine. It also could live up to its typical reputation and be a parts engine.

It is impressive what you guys can discern just by looking at a quick picture.
Yeah, I thought they looked odd but didn't really know why.

As they seem to be mostly parts engines, I am going to be posting this last bag-o-engines in the for sale section once I can figure out how to box these up and come up with a price. (Someone did grab the first bag).

And now I know what those letters are on the front of the blue head engine

The O&R is missing it's drive washer and prop washer. These are always missing. A Fox .35 version will work though. However, the needle valve is still there which is nice because O&R used the smallest spraybar for their engines making it difficult to source another. Many times the bolt on front blocks the displacement and O&R logo making it darn near impossible to see what one has. I see this one has it on the front of the venturi stack. There should be a W shaped piece of metal inside the venturi stack which the needle valve assembly passes through. If this isn't in there, the engine won't draw fuel.

            Bob , the older K&B Torps also had the round crankcase with ribbing on them. O&R used blue and also red anodizing on these engines towards the end. I enjoy conversations in regards to these engines. I have 3 running examples in new like condition which I enjoy just running. I run them really rich and slow and smoke the whole place up. The blue and red versions were detuned. The cylinders are not removable on a O&R. The jug is spot welded on and it wasn't uncommon to blow the jug off of the case so O&R really tamed these later versions down.

I gave up.
I couldn't come up with a reasonable price for the engines in the second picture so I posted them in the for sale section with "Make an offer"

I really appreciate all the information everyone here has given me.

If anyone who has posted in this thread (and lives in the USA) makes an offer on the motors, I would be happy to ship first.
Then if you're happy with what you receive you could then send Paypal or check, money order etc.
