Rick,

Verne wont be there, he will be either on his way, or in Portugal for the worlds.

Larry,

The other thing worth trying it find a setting that it will run at and just let it run for as long as you can. It might just need time. It might have gunk the pump or whatever. Also, lean the low end some, but it might just need run. The diaphram might be stiff and just needs sometime,
