Need help tuning Quickfuel carb

I’m just getting so irritated with this thing lol.
I’m going to put the Taylor wires back on it since it ran better with them.
I will put my modified cap back in double check rotor phasing to make sure it still looks good.
I do have a modified reluctor I can use to reposition the rotor if need be.
I’m also going to try it at 2500 with and without vacuum advance seenif that makes a difference at all.
Is it possible the little bushing the oil pump driveshaft rides in went out? And it’s causing the timing to bounce all over the place?
This engine doesn’t have many miles on it at all, it’s right at 30k miles.

If the timing is not steady, it's usually two things. Either the timing chain is loose or the distributor has too much play in the shaft. I shim my distributors so they have .010-015 movement up and down. And I run a collar on the shaft with ~.015 clearance.

Sounds like you have multiple issues.

Can we see a closer look at the plugs? I think you said you know the two cylinders it's missing on. That would be the two I'd want to see close up, and one that's not missing.
