[C320-list] Jabsco head dry resistance

[Jeff Hare]

Irv,

Before you do any more mechanical things here,  go to WM and get a bottle of their brand of 'head lube', put a few tablespoons in.  Give it one or maybe two pumps and let it sit for a little while.

Be careful when you try the pump next time, it usually works so easily you're at risk of pulling the handle off the pump and landing on your rump in the galley.  :)

You've been warned.  :)
Jeff
