When i took my valves off to clean them the pto side valve was hardly carboned up and the mag side was really bad. I was expecting them to be quite dirty because i never cleaned them for a while but im suprised as to why the one wasnt dirty. Does anyone know what would make this happen?

How is the piston wash/plug color side to side? If the PTO side is running a bit leaner (hotter) it won't build up carbon as much. How is the compression?

The motor hasnt run for a couple of months and it is out of my sled but i always check the jetting on it when i drive. I was missing a bolt for my y-pipe on that side so i am thinking that is the reason. I did a compression test on it in Dec and both sides were a little above 130 psi.

One side is a little richer than the other. Nothing to worry about at least.
