Hi everyone,

I was wondering if anyone knows about checking the distributor's vacuum
advance pump.  Are they supposed to leak?  When I hook up a Mity-Vac and
suck down one side it hold the vacuum.  When I do it to the other side
of the diphram it leaks down fairly rapidly.  Are both sides supposed to
hold pressure?

Thanks,
