"The answers to my questions will help you focus on the issue." HA, That's kind of funny Eric,, I do appreciate the help.
While the service manual only shows one pilot jet in the diagram on page 2-3 for illustration purposes, the carburetor actually has two, one for each barrel. Also the manifold APPEARS to be separate for each cylinder, I am not going to remove it to verify unless necessary as the coolant flows through it, and I didn't order gaskets for it. At this point I am thinking I may just have some clogging in the carburetor from old gas,, I believe this tractor may have sat unused for awhile. When I get some time (maybe tomorrow), I am going to run it with a big dose of Berrymans B12 in the gas then check the plugs and pipe temp again. It does run fine, just very lean on the right side,, enough that I won't use it like that. I'll keep you posted,, we'll get to the bottom of it. Thanks again
