Re: Poor Compression
Didn't take a picture when I found the problem. The upper portion of the seat was carboned up pretty badly. I then attempted to "lap" a new valve to see the extent of the carbon build up and pitting. There seems to be a lot of seat material remaining and I believe it will clean up by grinding with the proper stones. I have the correct set available but it will be a couple of weeks before I will have access to use them.
Here is a picture after "lapping".
