    Thanks for all the responses - I'm glad I finally found a club with so much interest in a mark. New question - after points, cap, plugs, wires, what might cause a slight miss, plus lack of power?

    Check all flexible fuel lines for a small pin hole. If air is getting in, you will lose power when your Jeep in pulling a load. KCJ

    Thankyou, is there a decent source for specs on the 67 4cyl motor?

    Install a Pertronix Ignitor, it replaces the points.
    It will really wake up the old Hurricane... do a search on Pertronix in this forum :)
