You seem nice & legit on the surface (good day btw) but for some reason, the anti-spam system red-flagged you. I'll stick it back but if you start spamming, I will give you a ridiculous custom title lol.
I don't know either...I was literally just responding to it now.
I believe you have multiple problems...everyone wants the quick and easy fix.
An old bike that's been sitting, is going to need the carbs cleaned, rebuilt and synchronized to run correctly regardless.
You have 2 coils...one looks after #1 & #4, the other looks after #2 & #3, so if 2 is firing, 3 is probably as well...but the carb is likely holding it back.
Pull the plugs and check for spark...you likely have issues there too...old coils, old wires & boots etc.
