On the subject of pump stick lubrication:  Animal fats eventually work
into the wood and dry out, plus fat attract insects and is temperature
sensitive (it hardens when it is cold).

I recommend using Sta-Lube Engine Assembly.  It's a lube with moly-
graphite.  Clean the pump stick junctions and sockets thoroughly before
applying new lubricant.

Sta-Lube is superior to "JAX" or anything else as it is a graphite- and
mineral oil-based lubricant that stays put and prevents seizing.  If
you can't find it locally, call 1-800-272-8963.
