I'm trying to verify that the PEVR I obtained is working OK. I applied 15 lbs of vacuum from a hand vacuum tester to the manifold side of the valve. It held OK, so the diaphragm should be good. Then I tried to blow air through the one of the top ports on the carb side at a steady rate. My cheeks puffed up and the air passed through to the other port OK. When I released pressure, the air still kept coming through and I couldn't notice much difference, but my cheeks collapsed slowly (No crude jokes, please! I've already thought of all of them!) as I continued to blow air. Does that seem OK? It seems as if vacuum on the manifold side only changes the back-pressure on the carb side slightly, but does not cut it off completely. Is that what I should expect if it's working correctly?
Thanks,
Dave
