I’m thinking the outside carbs are coming in around 2500, judging from my foot pressure on the gas peddle. I took the tops of the 3 carbs off this evening. The front and center carbs had these silver colored valve assemblies. The rear carb has a brass needle valve. I have enough to change the front and center to the brass needle valve. I’m hoping that the front carb wasn’t getting fuel. The photo from above shows the front carb is cleaner. Maybe this has been going on for a while. I poked a straight pin in all 6 jets, they were open. I’ll see if I can get it back together tomorrow night.

The silver ones must be a modern replacement.

Make sure you clean out your accelerator pump nozzles tubes in all three carbs.  They actually stop up with fuel contaminants quicker than the jets, and they will not give you that shot when the throttle blades first start opening, and that will cause the lean mixture.  Joe-JDC

Well, I got her out tonight for the 1st test drive and it isn’t the float needle. I can shut off the fuel to the outside carbs and loosen the linkage and just run on the center carb and see what it revs like on just the center carb.

It does the same thing running on just the center carb.

Maybe a bad fuel pump.

Are the other carbs set up as secondaries?  If not, you can swap one of those and see if it is the same.

We're at the cabin this weekend. A couple of minutes ago, the 3 legged bear was here. The front door wasn't shut tight, and he pushed the screen in and the door opened, we all screamed. I believe we scared him as much as he scared us.

Well, I’ve got an update. The last thing we decided out at Harry’s was to change the plug wires. I ordered some new ones from Mac’s. Got them on this weekend. When I looked at the old ones, one on the drivers side was missing the metal thingy that fits on the spark plug. I drove 130 miles yesterday to an AMC show and it ran great.
