My 1990 OMC 4.3LHO motor is equipped with an ignition module/coil pack and a timing sensor.
She starts just fine, however she idles really high, or isn't idling at all. She goes straight to 1500+ rpm's. Have adjust the fuel/air mixture on the carb (4bbl Holley). Have adjusted the idle mixture screw.
Any ideas?
