Alright, well I picked up a Holley 2300 2bbl for cheap that's in great shape. I'm going to go through it anyways and clean it real well and put in a rebuild kit with new seals and accelerator pump to make sure it's 100%. It's a marine model, so it's got an electric choke and the fuel bowl overflow points back down into the carburetor. All I have to do is change that with a Dremel and then decide whether I want to install a manual choke kit or wire up the automatic choke if it works. I called Holley and they couldn't ID it other than that it is a 2300 model, but I'm guessing it's the 500cfm mode.

It's got 2 #70 jets installed in it, and my stock Carter YF has a single #70 jet. Obviously this thing is going to be running way too rich jetted that way. The smallest jets Holley makes is #41. Should I start at 41s, or does anyone else have any opinions?

I'm new to this forum and appreciate the detailed write ups.
There are several regarding the Carter Yf; but this one seems to address my problem. Running rich, especially at idle, with excessive visible fuel coming from the discharge nozzle.
Looking at my pictures and reading this post; I'm going to adjust my float and see if this resolves my problem. The float doesn't seem to have fluid in it, and I submerged it in near boiling water checking for leaking bubbles; it seems sound. Metering rod jet seems to be adjusted correctly, and pump diaphragm is new.
Could someone identify the holes I numbered? And does the discharge nozzle look damaged, and can it be replaced?

When I removed the carb, if I tipped it in the direction of the discharge nozzle, a steady dribble of fuel would come out of the nozzle. Is this because of the maladjusted float or is something else going on?
I couldn't get your civilianjeep links to work. It looks like you intended GIFs; but they're linked to an Ad site.
Thanks again!
