Sticky choke on the goofy 6 month 2 barrel carburetor.

It used to work and now it doesn’t. I lubed up the various parts I thought were responsible but no luck.
If I pull the cable, nothing happens. If I pull the air cleaner off and tap on it, it will close. Like the spring isn’t strong enough or something, but it’s sticking on something.
It was rebuilt in 2022, installed early 2023, and has maybe 20 miles on it since.
Any ideas?

Maybe the choke cable has a slight kink/bend on it? I use to pull my choke all the way, if I tapped around it I would then hear it close. Turned out there was a tiny section of the choke cable that was bent and causing it to stick.

It pulls back fine. The butterfly doesn’t follow it. I was told in my other thread that the rod might just be off center enough for it to get hung up on the side of the carburetor

More carb issues.
I seem to be down on power. I took the vacuum stuff of my carburetor because it was hitting the master cylinder (dual reservoir) and I guess it’s opposite of my distributor (1 is advance, 1 retard)?
A friend told me that the secondaries probably aren’t opening without vacuum.
I looked up a pic on Spector.
I don’t have the [1] piece, my used/rebuilt carb didn’t come with it.
I took off the big round/square ish thing.
How would I remedy this?

Found a pic of mine before I pulled the vacuum stuff of if it. It’s a little different than the Spector pic. Where would I plumb it to?

Hmm well it looks like you have a later styled carb (2f) on an earlier style motor (1f). Which is fine, they should work together fine. If you removed the big round thingy from your carb, I belive that is the vaccum diaphragm for the secondaries. The later carb like yours are vacuum acuated secondaries; so that's the easiest explanation as to why they arnt working for you. Early style carbs use mechanical secondaries.

Edit: so put back the round thingy and see if the secondary works.

This is a 1969 carb. It’s the goofy 6 month one that no one runs. Apparently the vacuum thing is for a throttle adjustment something or other (early smog?) and shouldn’t matter. I was wrong, the secondaries are still mechanical. it’s just slow.
