If its a 2 inch bore, I may have pistons and rings for it. Do you have the pistons out of it now? if so, there will be a casting number on the interior but you will probably have to wash carbon out in order to see it.
They are smooth running motors that normally require just basic mechanical work to get them running. If you have specific questions about it, I’d be glad to (try and) answer them.
Hope this helps.
Best,
