Jerry.....I'm sorry I must have missed a post. I like the aluminum
pulleys
you sent the picture of....any history?  Will they fit the 13B, and
if so,
where might one get their hands on one?   Thanks in advance for your
reply.

Paul,  I don't know the origin of the pulleys.  There were is a box of
misc. stuff that came with my engine.  However,  if Paul  thinks  they
are a good idea, I may have some made up.  I like the larger pulley as
it slows down the pump some.    I think that is a good idea, especially
as the operating rpm seems to be climbing.

My feeling is it is cheaper and better to make a cap out of 4130.
