Update.... rear end project is done, for the fuel issue, i refurbished the gas tank, disassembled the vacuum tank and cleaned it out, fabricated the tube to go from the crankcase to the carb, and installed the correct plug wires. It runs like a top now.
If anyone needs the tube from the crankcase to the carb, let me know, i made a jig so i could duplicate the one i made.

Next task...new wiring harness!
