re: "QUESTION:- OK, assuming you?re still reading, could the problems

points? And thus cause them to wear out so quickly?"
Given that the pumps are designed to operate intermittently, I'd say
no. Getting decent points seems to be a crapshoot these days; did your
points wear, or become pitted? I suspect, but can't prove, that
contemporary points use less tungsten--an expensive metal that, I think,
is a bit difficult to work--than older ones; perhaps just a 'veneer' on
a cheaper metal.
