Can’t set ignition timing correctly

I’m having trouble setting the timing correctly. I’ll set the left cylinder perfectly, lock it down, then check it again. Still dead on. I set the right with the same process. Get it perfect, lock it, and check it. When I get the right cylinder timed perfectly, the left cylinder timing changes.

I have a CMC electronic ignition.

I’ve adjusted the cam tensioner. I’ve tried cleaning, lubricating, and tightening the springs on the mechanical advance.

What else could cause my issue?

It’s a 74 CB360 and it is the shockwave EI. I’ve tried setting it dozens of times. It was doing the same thing with the points. I’m really stumped how it’s doing this but it is.
