    Default "1976 Johnson two cylinder. W

    "1976 Johnson two cylinder. Will rev from idle speed to fast idle while in gear, trolling, with no change in the throttle lever. This will last for 2 -3 seconds and then the motor returns to normal idle speed. Any ideas on what may cause this?"

    Default sounds like its sucking air so

    sounds like its sucking air somewhere maybe. could be a number of things but i would take a can of carb cleaner and spray around while running and see if there is a change in the idle. if so check the area sprayed for bad gasket or etc.
