[TMC] [Boatanchors] a stuck Jennings Vacuum Variable.

[Harold Hairston]

All;

There is a fairly new product on the market named PB Blaster. It is a super 
penetrant. Better than WD 40 or Liquid Wrench.. It is available in most Auto 
Parts stores. Be sure to get the "PENETRATING' formula. You will find many 
uses for it.

CAUTION; I HAVE NOT VERIFIED IF IT IS SAFE FOR PAINTED SURFACES.

Harold

I don't but perhaps some light penetrating oil into the thread mechanism?
Was it screwed into the stop hard?
