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?
