1939 Buick Special Carter vacuum sw shims

Recommended Posts

Hello Amigos.

After installing an electric fuel pump and bypassing the mechanical fuel pump, the ol' girl is still very reluctant to start.

Found a couple paragraphs in the shop manual that talk about adding/subtracting shims inside the carb vacuum switch.

I'm thinkin' I don't have any of these shims in mine.

Question - anyone recall how many shims they have in their Carter WD-O vacuum switch?


Thank you!
