Thought it was worth a try. This engine is junk and going for scrap in a few weeks.
Is the carby any good? Might be able to put it on a really big saw...
What happened to the engine? Blown gasket? Hole in piston? Needs rings? If it's any of the above, it can be repaired quite cheaply, if done by yourself, not a shop.
