This engine showed up in a collection of stuff from a friend that passed away. It has no markings on it other than the number 16702 on back of the crank case. It has an 11" prop mounted on it. Points are missing and it has a Champion glow plug installed. Can anyone tell me what I have. Make and size would be great.

Looks like an O&R

O&R 60

O&R side port .60. They made a front intake model also. If you want to see and engine really shake, run that on that glow plug! No more than 5% nitro and plenty of castor.
Type at you later,

Does it shake as badly on ignition?
-
The ignition points and timer arm are missing so somebody intended to run that on glow-or they just removed the parts to use elsewhere. During the ignition-to-glow transformation in the late 40's quite a few made this change. A little unusual to see it on a side port. Much more common on the later FRV, front rotary valve engines. These weren't designed with glow fuel in mind (being a pre-war engine) and they often literally blew the one piece cylinder/sleeve right off with much nitro. On the O&R's this was spot welded on.

You have a late 1941 Ohlsson .60 Special. As said before, the timer has been removed. Later on, Ohlsson manufactured a Front rotor conversion kit for the sideport .60 engines. You had to cut the sideport off, and block it with a cork supplied with the kit.

OK, now I know that if I see an O&R sideport 60 with a freaking 70 year old rotting cork in the side port, I may not be looking at some basement hack, but rather a factory approved modification.
This is doing very strange things to my sensibilities, starting with "Just do what the factory says. The factory always knows best."
-
I have at least one with some sort of a metal plug. I assumed it is factory from the production line using a supply of stock cases. I think I have had or seen one with the cork. It keeps wine for generations.........

Thanks all. O&R 60 it is. I am tasked with the problem of selling it for a Church friend. Any Ideal what's a fair price? It has great compression. It is missing fuel tank, points, and spark plug. Every thing else seems to be OK.

If you can get 30 bucks you should take it

Yeah not much, especially incomplete. You can buy these on ebay in like new condition for $50-70 bucks sometimes. They are one of the most common old time engines and this one would really only be used for parts-no usable value.

I don't consider the O&R 60 sideport a "shaker". It is a bit rougher compared to most modern 60 glo engines. The late George Tallent, of Arizona was able to balance the cranks on these old engines, which made them a little smoother. Here is a "rebalanced" O&R 60 on the test stand.

I still have my brother Bob's side port O&R 60. We fired it up in the basement when I first moved back to KC. Has a hole in the side of the crankcase below the intake port. My brother said no problem. Only prop I had was top flite 12-6. He filled the tank and prime it. Hooked up the battery and put his thumb ove the hole in the crank case. It fired off first flip. Glad we had small tank on it as it got smoky. We did get yelled at. But it was very smooth running what time it was running. My brother said it was always an easy starting engine. It is stashed in the shop some where. D>K
