Exclamation Assistance with Ignition Issue

So, my son and I were replacing the cap and rotor on our 1970 C/10 250 and we incorrectly reconnected the plug wires and started the engine with the sparkplug wires crossed. It ran rough and smoke came out of the air cleaner nozzle.

I shut it down and we connected the plug wires in the correct firing order and it now won't run right at all. It stumbles as though its running on two or three cylinders and will not increase RPMs above idle.

I inspected the points, which were pitted and also noticed that the wire from the coil to the point had lost most of its insulation, so I also replaced that, along with condenser.

So here is where we are today:
New cap
New rotor
New points
New condenser
New wire to points from coil

Here is what I know:
There is spark
There is fuel going to the carb
It starts, but won't run
Timing was correct before this issue started

I am wondering if I damaged something in the carb when it backfired?
I am also wondering if the timing is now off for some reason?

Any assistance is appreciated.
