New set of nonresistor plugs NGK. Ignition wires are not resistor wires they measure 1K ohm.WUR is operating as it should. About 15° advance. All cylinders are firing. What affect does the vacuum have on the control pressure when it idles? Still no change starts and idles. Only about 600 rpm. After about 30 seconds rpm decreases then it quits. The wur is set at 22 psi. Maybe that is not low enough? Maybe another 5 psi lower...17psi.
