The last items on my winterizing procedure include draining the main passage and emptying the sediment bowl on the fuel pump (mechanical). I do both with a plastic deli container. The flexible container can be wedged to get below the passage plug and catch any fuel from the carb. I position the same container beneath the sediment bowl on the fuel pump, loosen the bail and drop the bowl into the container. I have a Racor and polishing filter but have had issues with ethanol killing the sediment bowl gasket and gumming up jets. This practice has eliminated those issues, though in the spring I'll often bring home the carb for a quick rebuild. Take care of her and she'll take care of you
