Someone here must know who makes this engine. I have two of them, and Troy-bilt has parts for them, but I have yet to identify who makes the engine.
Has anyone ever used one for r/c?
How would you mount it? The "oil pan" is mounted at a 45 degree angle making mounting awkward.
I have the other one swinging a 20 inch prop and it seems rather strong for a 4-stroke and stock emmision carb.
The one shown is just goofing around, I haven't run it yet I need another rocker arm. It was an E-bay cast off that dropped the head off the intake valve. I made new valves for it, now looking for another rocker arm to get it running.

I think I have too much time on my hands.

I believe it is a Ryobi, I have a early Ryobi 4 stroke that looks just like it, I think is in 22 - 24 cc displacement.

I intend to recycle it into a plane when my lathe is up and running. Not a lot of power, but will work fine in a floater like a Cub.

I believe my oil pan is aluminum as opposed to the later model that used a plastic oil pan.

I ran mine for 10 years as a weed eater, the local repair shop told me he hadn't seen any of them live that long.

It should be a fun motor, I just love that putt, putt, putt.

As I recal there was a thread or two on this engine including a pattern to make an engine mount. I don't know how far back though, maybe a few years now.

Could you talk a little about this process?
alloy,machine tools used ,heat treatment, etc.

Thanks for the info. Here is a picture of the other one that is stock with a prop. It runs ok but anything over 1/3 throttle it slows down because of the econo emmisions carb. Being over proped may have something to do with it
I make my own valves out of drill rod and left un-hardened. I will bet they outlast the rest of the engine. I build running model 4-stroke engines as a hobby and drill rod or"silver steel" seems to work ok for valves. Allthough the engines aren't run that hard.
I will find out if it works for this application or not. The original valves are two piece, the head is pressed onto the stem. The stem broke off just under the head of the original valve. Beat things up a bit, but didn't hurt the seats.
This is just for fun anyway[

Looks like the picture didn't follow me.
