RE: How to rejuvenate a long stored OS 1.08 ?
Thanks to all who replied to my request for info. I ended up soaking the engine (carb included) in denatured alcohol for 1 day. That got everything loose again so I then filled the engine with a super penetrating oil and let that soak for half a day. The bearings looked OK so I put it all back together and mounted it on my test stand. It fired on the first flip and ran well at low RPM but died due to overheating when I ran it at high RPM for about 30 seconds. I let the engine cool and restarted but alternated between high and low RPM for the rest of the 12 oz fuel tank. The engine seems OK now but I will probably bench test a little more. The bearings seem OK but may still be a little tight from congealed castor which would explain the overheating. Thanks again
