69 RR engine miss/stumbling when warm

[Bcamp69]

So many things wrong in the old pics and most of them are mentioned, did you remedy any of these?

Kickdown linkage is proper now.

As for the the vacuum advance, I'll probably just leave it on manifold vacuum for now.

The electric choke is operating properly.

I've got new set of plugs. It has AC Delco R43's in it I've got R45's to replace with.

Just got the timing light and vacuum gauge. I'll be adjusting the carb and checking the timing today or tomorrow. Although it idles and runs smooth I can't imagine the timing is very far off.

Aside from the kickdown linkage, what else is wrong in the old pics?
