Just an update --
Started truck and adjusted timing to the BB. Checked a few miscellaneous items mentioned - carb power valve, fuel filter, gasket under carb, etc.. Started it again - still bad.
Distributor is 1112403-6L29 with a tall cap.
Only had a few minutes last night. I tried to adjust the dwell and I think a moved it too far since I can't get the truck to start now. Having a friend that is more experienced setting points to come by this weekend. Will experiment with different settings. Will post more information after that.
Thanks everyone for the help!
