Have you checked thermostats?...clip...

I will. Best to anyway.

I couldn't just step away. I'm so obsessive compulsive.
I pulled the thermostats.
Again, everything is clean inside.
It's obvious the ol fellow was religious about taking it in for service. The bolts weren't corroded stuck at all. Around the hose connections were a little over done with RTV, but still...
.
I guess I put them in water and heat the water and see what temperature they open at?.
.
One of the white plastic things with the cross just fell out, the other wasn't stuck, but didn't just fall out. I don't know if that means anything that both didn't just fall out.

Since this thread has gotten long, and since it's about possible air/fuel issues, I won't include my ignition troubleshooting here.
.
Once I get done verifying all the ignition stuff, and if I don't find anything wrong with anything related to the ignition, I'm going to try checking the primer solenoid. I read in another thread where it was stuck pumping fuel.
That would relate to my plugs being so wet.

The electric primer is NOT a pump.-----It is a valve.

Yeah, sorry. If the primer solenoid valve is stuck open and the fuel pump is pumping, the fuel would be just 'pumping' on through the primer solenoid straight to the carburetors, correct?
