I am rebuilding a TO-20 for my wife. It was her pappys tractor.
When I took the head off all the pistons were evenly coated with carbon.
The exhaust valves were all not the same color.
I was really confused after cleaning off the piston tops. All I notice is the direction indicator and the letter "P" stamped into the top. I was expecting "STD" or something like a number indicating a over sized piston. What does the "P" stand for?
