I agree, this engine has ingested tons of dirt and needs a full rebuild which I am planning on doing. I wanted to get it in a cleaner condition before I take it to my engine guy in a week or so. I will pick up the Puma 2110 turned into a 2276 Type 1 engine and drop this baby off. It will save me some money to have the engine degreased. My guy charges by the hour not a flat fee. So far the engines he has rebuilt for me come out super reasonably priced.
The seller had in his listing that the engine had 4000 miles on it but had low compression in number 2 cylinder and was smoking a bit. He thought it was a broken ring? I now know that is unlikely. The engine is probably worn from the dirt that has been sucked into it. My original plan was to re jug and piston it and have the heads rebuilt and not crack the case open. That plan has changed. The last three engines I have had rebuilt all have flattened cams among other issues. Seems to be an epidemic. I know why Chris went to EV power now. Driving in such dusty conditions is hard on internal combustion engines unless you run a good oil bath air cleaner and keep the oil in it changed regularly.
