53 Buick carb issue PLEASE HELP!!!!!

First, I want to thank eveyone for not getting on me because it's not a Mopar and also for the help.

I completely soaked the carb in the "good stuff" for a night. I blew out all the passage ways and even ran a wire through them all to be sure I got all the crud out. Yes the check ball is installed in the bottom of the pump well. There is also a small weighted check valve under the screw for the squirters, and that is installed. I noticed that I have a small shot of fuel at the end of the plungers travel in the well.

Badsport, the original plunger was missing the leather. the new ones only come in leather. I wish it came in the neoprene like the quadrajet carbs and so forth.

RRR, ya the garter spring is in there. I thought the same thing that maybe I had to transfer it over from the old one but it did come with it.
