Here's what I do it atleast keeps any substantial dirt out. Steal an old set of your wife or girlfriends panty hose and cut out a square big enough to stretch over the carb opening, then just attach it there with a small zip tie, works great for me. Hope my wife does'nt see this. Good Luck, Kevin.
I'd put them back where i found em with the little square gone. Just for sh1ts'n'giggles.
