UPDATE!!!
Since I had a few spare 6602 parts,I swapped the carb Sun evening,that cured all of the idling/running problems,truck starts easily, idles smooth and accelerates quickly.
I spent some time this evening installing a alternator conversion kit and working on the lights,with the exception of 2 blackout markers,all the lights work.
I aired up all the tires as well,adjusted the fan belts,and have the compressor belt pulley soaking to adjust it tomorrow.
I ordered a set of manifold gaskets today,should get them installed this weekend if I am here,after which I'll post another video of it running.
