Progress is slow on the 301 gasser. Block is cleaning up well. Still haven't gotten the head back from machine shop. Had some diesel cylinder sleeves out of yellow project #2, the 301A tree flatten father & son project. They had about .003 wear on them. I almost started to cut them down to fit the gas block. But after searching online, I found some NOS gas cylinder sleeves. So I went with them instead. Here is before and after block pictures and the diesel sleeves almost getting cut down on the lathe but didn't. Yellow project York and getting a Yanmar running again that had a seized up injection pump are keeping me side track a little.
