Re: An Air Cleaner from a '33 - To Clean or Disassemble

I've used a Mityvac and the Bijur's diaphragm is good. When I cycled it vacuum/no vacuum, it would not pump oil.

Great little tool, that Mityvac!!! No one should be without one. If you only cycled the pump with the Mityvac 5 or 10 times, I wouldn't expect to see any oil emerging yet from the outlet - try 50 or 100 cycles. And of course first make sure the inlet screen/felt is clean.
