Chuck,
I use a mityvac silverline metal vacuum pump. They cost about $10-$15
more than the regular plastic one but seem to last longer and rebuild
kits are available. I apply about 15" of vacuum to the unit and it
should move (mine does but it leaks down the vacuum really fast) so I
assume the internal diaphram has a leak plus if I pour oil in it it
holds longer so there must be a pinhole in it. I do not look at the
baseplate but at the spring/arm coming from the diaphram(disconnect it
from the base plate). If the spring moves but the baseplate does not
then the baseplate is probably frozen.
The vacuum pump is available from HarborFreight for $49.99

They are having a cybersale this weekend so it may be even cheaper than
that try them this weekend Aug 1st & 2nd. http://www.harborfreight.com/

Peter S.
