Holley/Weber or Weber use on a sandrail?

[Stinky]

I'm having a bit of a disagreement w/a guy. He doesn't believe that a Weber progressive carb, or a Holley Weber carb is prone to having the secondary pivot arm and etc are prone to getting sand in there and then sticking.

Anybody had, or not had that problem? BTW, if you've had it, it is good for a thrill.
