Denny, you are fighting two different problems. The coil and or condenser fixed the back firing problem, as of two drives that is gone. The hesitation off idle is a carb problem.
The two are not related. Even vacuum advance won't cure a off idle bog. Vacuum will drop off when opening the throttle so the advance is backing off by the time you are rolling. The mechanical hasn't moved yet ether due to rpm. Don't bother with the fuel tank or lines, they sound just fine and your ten mile drive proved that. If it runs at full throttle or even after it bogs a bit, your fuel system is working.
Check the accelerator linkage and pump. It should shoot fuel just as soon as you touch the throttle. If not bend the linkage or adjust what ever is there so it squirts fuel as soon as it can. You may have to play around with it a bit.
