Robin,
I hate doing it this way, but it will be clearer. I didn't have time for 11+ minutes of youtube - sorry.

Why would the pump slow all the way to a stop? I mean, is there some sort of sensor or logic in there that somehow lets the pump know "Hey, the bowl is full and the float is blocking any more fuel coming in, you can stop trying so hard now, okay?"

No, the pump is internally leaky. So, it pumps a bit of fuel and even if it does not get used, the pump's piston gets pushed back by the spring and it does another stroke.

Quote:

I've been operating under the impression that fuel pumps run at all times, and that it's up to the floats in the carbs to control how much of that fuel actually goes into the carbs.

That is correct.

Quote:

For sure it's connected properly, and it works: I even unhooked the pump from the carb and hooked up power and watched it pee fuel onto my garage floor.

That was another good test, but when you try this again,plug the gas line with a finger. The pump should go into slow pump mode.

Quote:

I can hold the carb up to my mouth and blow into the fuel inlet with the float hanging down. If I lift up on the float, simulating it floating in a bowl full of sweet sweet gasoline, it blocks off something and I can't blow through it anymore.

That is another very good test.

Quote:

It's behaving as if, the float is stuck in the "up" blocked position, preventing fuel from entering the carb at all. I don't think the bowl is interfering with the float, and the float certainly seems to move up and down freely.

If you can't figure it out. Try the blow in to fuel inlet with the carburetor loose. Then turn it upside down and see if it shuts off. I have cases where the assembled parts do not behave correctly.

Quote:

I'm going to put some more gas in my fuel can, to make absolutely sure that the end of my fuel line is drawing fuel instead of air. Then i'll take the carb off again and see if the bowl fills, and if not, see if taking the bowl off changes anything; that will tell me I've got something going on with my float.

That is a real good plan. Your analysis and thought processes are going to be a great asset.

Quote:

There was no seepage around the unclamped hose that I just stuck onto the carb fuel inlet, and there was no fuel coming out of the carb.
