Got everything apart and had my mechanic buddy look at it. He said the jugs are salvageable, but one of the jugs may beyond the point of honing... So maybe a .20 over kit may be in my future. I could feel the grooves with my finger nail. Ran way too lean for sure. The top ring on the PTO side was seized.

I am going to take my jugs to a local machine shop and get them done right. The bottom end seems to be ok (whew).

Going to go with a SPI kit.

Both pistons had some seize marks, but overall they weren't horrible. Could have been MUCH worse.

Here is a picture of the piston at 90PSI. Most the damage was on the exhaust port on both pistons... This one being really bad, and the other just some light scratches.
