When working on my carburetor last week, I dropped one of the four screws holding the bowl to the body into my bilge and cannot find it. Do any of you know the screw size for the bowl to body screw on a Zenith 68 carb from a 1982 Atomic 4? Please leave an answer here or write me at pdecker@sailnet.net. Thanks.
