I'd go a head and use manafold vaccum.
A vaccum can/resivore of some sort may help as well.

I've already gone elect. found my vac unit is fine, the motor has major vaccum issues - as in leaking intake gasket.

Nutherwords, my orig vac motor is for sale if anyone needs one.


it ain't YOURS 'till it ain't stock!
