Hy Rusty Shackleford, I assumed you had a Rochester "B" on your engine, and we all know what happens when you assume things. I had to do some research on the Carter W1, in the book it talks about a sealing washer around the metering rod, and the small gasket between the air horn and the carburetor body located at the air passage between the air horn and the fuel bowl, and that the fuel bowl cover gasket is in good condition. The sealing washer which the metering rod passes through the top of the float bowl cover must always be in place. Both the conditions mentioned above will admit atmospheric pressure to the float bowl and cause excessive gasoline consumption, especially in the intermediate driving range and defeat the purpose of balanced carburetion. I have tried to find a carb kit number for that carb that you could purchase at Lordco, but so far all I can find reference to is the YF model, I will keep looking. As I said before, the state of tune, the quality of the fuel, the cleanliness of the oil all contribute to passing the Air Care test. Carb gaskets and seals can shrink when the carb is allowed to dry out, methanol in the fuel is actually corrosive when allowed to sit in place for long periods of time. If your vehicle is going to sit for extended periods of time, you should run the engine until it runs out of fuel, hope that helps.
