I have recieved a few of these type of engines over the past couple of years. At the beginning of this year I decided to try to get 4 dirty, rusty, siezed up engines to run.
The first thing I did was get some machine tool oil and put it into the motor, I put a couple of drops in the carb it I could turn the prop, if not I took off the muffler and droped it right in.
After a few turns things get loose. I then tried to run the engines on my test bench, 4 of 5 came to life very easily!
I then turned to cleaning the engine up. This was pretty simple WD-40 and a toothbrush. Spray the WD-40 on the engine and let it set in for a couple of minutes, then start scrubbing. The result for me was a bunch of old engines that look almost like new again. The WD was good at getting the old fuel off and all of the other crud on the engines. The one engine I could not get going I cleaned up and took to my club, where a guy who really knows engines helped me get it up and running (took all of 10 min for him)
I now have:
1 OS .61
1 OS .30
1 OS .25
1 MAGNUM .46
1 MAGNUM .25
None of which were running when they were given to me, all of which are now good to go into any plane that they will fit. It took a couple of hours over a weekend.
Nice supply!

I did not include the ones that I have actually paid for:
OS .46 FX - Mounted on a PT-40 trainer - waiting to move up to a GP Corsair
OS .25 LA - Mounted on a Sig MK II
OS .91 Four Stroke - Will be mounted on a Unionville Norseman (on floats)
I am thinking of mounting the OS .30 into a trainer I converted to a tail dragger, and the .61 will go into a Sig 4* that I will buy this summer. I have another plan for the .25 - SPAD combat planes! Fast, cheap, durrable and fun - how could they be put to better use!
