It's becoming a problem.
In the 4 years since I've been tinkering with A Bodies, I've now had 3 Slant cars - the previous two both had Holley 1920s, this Signet has an abused BBS.
Unfortunately mud daubers rebuilt the BBS before I got ahold of it (vent and fuel inlet packed full). I've rebuilt numerous carburetors over the years. Mostly Quadrojets and Dualjets and the 1920s of course - this will be my first BBS.
While I wait for a rebuild kit to arrive, I disassembled and cleaned the carb. Interestingly enough, there were zero check balls in it and the screws have been overtightened to the point of distorting the fuel bowl and air horn.
