I recently traded for two NIB OS 32 F engines. Both had extremely rough inner bearings and I changed them out before running them, which I have yet to do. These are intended for a twinstar and should be about right.
These are the first 32 F engines I have encountered, I know they languished in a wood shed for about 10 years in their origional boxes, thus the rough bearings? They looked great when removed, but were rough.
Can anyone tell me about these engines..........
Thanks,

I campaigned several OS .32F ABN engines in competition fun flying some years ago. I was very happy with their easy handling, excellent throttling and exceptional power output.

Their break-in consists of being ran in a slightly rich two-cycle using a 9x5 or 9x6 prop. A 10x4 or 10x5 will work as well. Just don't even slightly over heat the engines during the initial runs, but never run them in a four-stroking mode. The liner plating is a bit delicate. You don't want to start them peeling, though one of mine continued to run fine after peeling had begun. I never did get around to getting the liner replaced, but instead put a LOT of operating time on the engine.

As usual, run fuel with a bit of castor in the mix. My versions were not particular about nitro content, either high or low.

You will love these engines. I envy you.

The 32F was a predecessor to the current 32SX. They ran pretty good

The engines are wonderful, your original bearings probably had congealed oil in them making them feel rough.

Thanks guys, I really didn't find much to indicate old oil in the bearings. I decided that I didn't want any foreign matter in the engines so the change in bearings, far cheaper in the long run. I have a total of $32.00 in both engines including both new bearings ($12.00 at the local bearing house).
I will soon be running them in.
