Here are some pictures of the cylinder after tear down. The third picture shows the top piston ring inside the cylinder. There is quite a bit of cap between the ends of the ring. The cylinder itself is in EXCELLENT condition!!! I was very surprised at how smooth it was.
Here are some pictures of the crankshaft journal and the piston. The journal and crankshaft are in great condition!! The piston is in fairly good condition but I am going to probably replace it and the rings.
Here are some pictures of the carburetor. It is in fairly good condition. It is missing the piece of metal that slides into the throat of the carburetor. Is that easy to replace??? I have a spare carb laying around that I can take it out of.
Here is a video showing the play in the valve guides. I am not sure what is allowable or not. So any feedback would be greatly appreciated.

Here is a video showing the play in the throttle shaft of the carb. Again I am not sure what is within spec or not???

I plan on taking the block to a local machine shop to have the cylinder looked at. It looks to be in great shape but I want to see how even the wear is throughout the entire cylinder. If it needs to be cleaned up I am going to let them hone and bore it if over.
All input is greatly appreciated!!!
