I had a similar problem.  I put a sock over the snorkel to keep the dirt out of the intake before an off road excursion (the guy at the shop said put a sock on it but probably not an old one from my sock drawer). Anyway, it ran terrible until I pulled over and took it off. I laughed like a mad man also.
