Hello. Is there a simple way to test a VA when it is taken off the distributor. A buddy of mine brought over what I call a vacuum tester. You stick a rubber hose where the vacuum line goes and pump up by hand. Is the VA arm supposed to hold in place or when you stop pumping return back to where it started?? Also is there any kind of gasket that goes between the block and ditributor flange?? Thanks, Brian.
