Subject: Ignition coil problems for CB160

Hello I'm not getting my right cylinder to fire. The left works fine. When I put an induction timing gun on the left side spark plug wire the strobe works fine. When the gun's clip is on the right side spark plug wire there is no strobe from the gun. When I take the plug out on the right side and turn the motor over, I see a spark, but there is no firing on the right cylinder when the left side cylinder is running. It seems that only the left cylinder fires and pushes the right with it.
This has been a long project and a complete restoration on a 1965 with low original miles. When I first cranked it both cylinders were working for a short time then the right side quit.
I thought it must be a bad original ignition coil so I replaced with a nos part. Same problem with replace nos coil. I have replaced all of the original electrical components. This is the type II engine. The two cylinders fire at the same time and there is only one ignition coil with two spark plug wires coming out of it.
Does anyone have any advise about what I could look at next or why the right side cylinder would not be firing? Was I wrong about the ignition coil being bad? Thank you for any advise.

I know this might sound stupid but have you checked the boot on the spark plug wire? Or the ignition timing? Had weak spark on 1 cyclinder causing it to occasionally fire changed spark plug boot an reset gap on points now runs like a scalded dog
