/6 wont start/ run with choke

The problem is, it acts exactly the same with another carb so personally I believe the carb can be mostly excluded as the culprit of the issue.
I need to do a compression test but my compression tester disappeared with a lot of my tools on the move to Idaho.

I’ll check the manifold for cracks or leaks too but those usually run better with the choke on don’t they?

I was hoping someone had a simple explanation. I just want to drive anywhere, anytime with no problems and to keep it completely stock.

So you tried 2 carbs and it didn't change anything? I think I would move on from the carbs and try something else. Like items mentioned in post #3.

What is the choke actually doing? On a cold engine, depress the gas pedal and check it out with the air cleaner off without starting the engine. Where is the choke plate on an idling warmed up engine?

You can rent a compression tester from one of the larger parts stores for free.
