Might want to do a poor mans resurface like I did here.
Yeah, it might have to wait for the first oil change ( which will be soon) but that’s a good idea.

Bob, just an FYI on the XS2/TX650 carb enrichment system.
Unique to the 72-73 carbs is the single choke in the left carb, which has a crossover tube to feed the right carb. As such, the choke fuel pickup tube is in the left carb only. Using your carb pic, here's the choke fuel routing.
View attachment 137659
Fuel is drawn up thru the pickup tube, and intermixed with air at the front on the carb.
1- That air/fuel mix emerges to the bottom of the choke plunger.
2- When the plunger is raised, it's mixed with more air and delivered to the "C"-shaped channel. This zone is shared to the other carb.
3- Where it emerges into the carb throat.
The "C"-shaped channel will always be at a vacuum. Which includes its port/passage astride the choke plunger. Ensure that the plunger gasket seals between points 1 and 2...
Float seat can be tested with bowl off and hook up fuel(with cup underneath carb to catch fuel)...
Manually hold float up and no gas into cup, let it drop some and flow...
...and on the needle valve the tiny springed tip at opposite end of seal must work...push it in and see it return freely...
...kind of starting point to see where you at maybe...
+1 on the clear tube method. You inadvertently proved the carbs are overflowing. The needle and seat should and I stress the word should stop all fuel flow. But they are not fail-safe.
Go to robinc's thread and read #388.

You may have more than 1 problem, float level is the place to start.
How are you going to be able to fix the paint on you cases. I almost cried when I saw the pic of the fuel damage to the paint.
....you must be getting awfully good at R&R-ing those carbs and airboxes Mailman....
