Great info; and, as a clarification if there is any confusion... (and to validate that I have read AND comprehended all carbking/HRL/others carburetor advice here on Stovebolt):
I have a Carter YF 2100s installed on my 55.2 truck's 235, and I have an identical spare Carter YF 2100s ready to install should it be needed.
I will not be purchasing a Rochester B(or BC) rebuild kit for the ones I have that need rebuilding.
