Thanks J, again, I really do appreciate all the feedback. Parts should be here soon. I went out to the garage the other day and spun the flywheel several times. It spins pretty smooth for the overall condition of the tractor. I will definitely get the injection pump flushed and cleaned well. While I'm waiting, I might as well clean up the tractor and make it look more presentable. LOL
When you say cam box, are you referring to the cover on the side of the pump with the three bolts? (See picture) Apologies for my ignorance.
It's in my best interest to do everything I can as you said. Rather be safe than sorry for sure.
