Should I worry about the carb or just drain it and shoot it with carb cleaner?

"Seems if I pump the brakes they get firm at a higher pedal height. If I'm cruising the first time I hit the brakes they go down a bit further."
This is a very common problem with 521 trucks. The wheel cylinders have only one port for fluid and air to go in and out of. You have to allow the brake shoes, and springs to collapse the wheel cylinders, and push any air in the cylinder back out to the bleeder valve. If you use a pressure or a vacuum bleeder, the exchange of fluid for air never happens in the wheel cylinders.
Bleed the brakes manually, with two people. The person under the truck has to open the bleeder, when the brakes are applied, and the pedal has to go all the way to the floor, and held there. With the pedal on the floor, the person under the truck has to wait until all fluid (and air) flow stops. Then close the bleeder. Then the pedal can be let up, slowly, and pushed again. Three full pumps, and refill the master cylinder.

This screw was just sitting there not threaded. Too small a screw and probably why I was getting water in the tank
I can't seem to find a sending unit o ring anywhere in town. If I understand it correctly it should be a 2.75 inch o.d o ring. A service manual shows what looks like a flat type gasket on a 521 and a o ring type on a 620. i guess I'll pull it out and see exactly what size type it is. I'll need to find a larger screw that will actually tighten and seal too

Took the new blades apart and used just the rubber.
Saved the metal strips from the old blade so it would line up with the old arm.
Just trimmed it to fit and slid them in.
I used needle nose vise grips to squeeze the metal past the prong to get it out.
Now I can drive in the rain and only deal with my bad windshield!!

That's pretty common. Use loctite on them when you install the new ones.
I have a trick that solves this issue. If you have the cast iron bracket, using a 3/8" drill bit, drill out the length of the bracket to be able to use one long bolt with a nut on the other side. Use an old head bolt (or whatever) and you'll never have that bolt come loose or break ever again. You will have to drill the alternator to 3/8 also.
