You have made a classic mistake that many lads make. You have changed too many systems on the bike at one time. You changed the alternator charging system, the ignition and the carbs all at once. That makes it difficult to trouble shoot.
Here's my suggestion. Remove the PMA and its rec/reg unit. Remove the Pamco ignition. Re-install the stock alternator with its stock rectifier and regulator and re-install the stock points ignition. Re-install a battery. Now the only new system is the carbs, so you can focus on getting the engine started and running with the new carbs, as the only questionable problem area..
Once the engine starts and runs normally, remove the points ignition and install the Pamco ignition. OK so once again, you have added only one new additional system. Focus on starting up and running with the Pamco.
Only after the engine starts and runs reliably with the new carbs and Pamco ignition, do you remove the stock alternator charging system, and re-install the PMA and its rec/reg.
Actually, I would just keep the stock alternator charging system/battery and forget about the PMA/capacitior crap. That PMA stuff has caused many problems over the years, and is an inferior system compared to the stock system. The PMA systems can also burn out the Pamco system (when the volts go crazy), while a stock alternator system with a battery, will not do that.
I also noticed your ATU fly-weights have a lot of wear on them, which means the advance curve will be expanded, and if you set the timing at the F mark, you will be past the fully advance mark. Running past the full advance mark could destroy your engine, when a hole is burned into the top of a piston(s). If you plan to stay with the Pamco, which is a good idea, it would be wise to buy the Pamco
E-advancer option.
