The rings were just rusted fast .I wouldn't be surprised if they might be okay .Never the less I'll use new rings on the assembly.

The spark plug was missing ,I ran a tap through it to clean the threads .Evidently for whatever reason it had just rusted up from sitting in some damp place .It didn't have any sign of galvanic reaction so it wasn't on concrete .

I have used the plug/grease gun method on a lot of stuck engines .The last I did was a 300 cubic inch Ford before this saw engine .That one was a hoot .I had all 6 cylinders full of penetrating oil for about a week,knocked it loose with a grease gun full of oil then rolled the engine with a big wrench  .Then lost my concentration and rolled it with the starter forgetting all the oil in the cylinders and drowned myself with oil ,duh .When I got it started and came out of the woods my wife came running out of the house shouting "the trucks on fire ".That thing blew blue smoke for at least 10 minutes .So much for the idea of drowning a plug with too much oil in the mix ,never fouled a one .
