All of a sudden my floor pump only works on my back tire! Last weekend I couldn't make it inflate the front tire, so I rode past my lbs, and they popped on their floor pump, and it worked. Makes no sense to me. One of my neighbors who's a bike guy suggested I let a little air out, then spit into the valve, then try. He said that will help get a seal. In case it matters, I have shrader valves.

Ideas?

Thanks, guys.
