My '88 Westy was experiencing hesitation when cold. You would take off
from a start and at about 2,000 rpm the engine would ack like someone
shut it off. Flooring the gas pedal would cause it to bog but then
recover.

Well, I thought I'd pass on that I replaced my Temp sender II (in the
thermostat housing) and the problem has (so far) disappeared. I'm not
quite sure how they are related, but thought I'd post the results in
case anyone else is experiencing the problem I was having.
