/6 carb help

Weird, they list your kit right on their site as a № 5560. Maybe they didn't understand your question, maybe they've have changed their biz model, or maybe they were sniffin' gasoline when you called. Oh well, there are ways around that. Pick up a Walker rebuild kit № 15560D, a Walker float № 100-13 (nitrophyll foam as original) or 100-48 (brass), and if you rilly want to do it up right, also snag a new old stock Tomco № 5302A kit for a couple of reasons: it means you'll have a usable float gauge (no brand of carb kits today comes with them any more; instead of the die-cut cardboard float gauge you get a useless strip-of-paper ruler), you'll have extra gaskets and parts for use now or later, and if you're lucky you'll have that new-design inlet needle/seat valve, which Daytona Parts calls the "Daytona Float Valve" as if they invented it, but which was called the "Duro-7 inlet valve" for many years by Tomco, back when there was money to be made by putting out a better carb kit than the other guys.

(…or you could just snag the one dude's two 5203A kits…)
