    Bill, clean the crackers out of your bed and fix your temp guage.
    Don't run the cardboard too long in the spring season, very easy to overheat on a warm afternoon.
    Yeah, don't ask, you don't want to know....

    Had the same thing happen to my old CJ7. The heat riser pipe was missing, my girlfriend and I spent 2-3 hours driving to my brothers place in a blizzard. I stopped in a heavy truck place off the beaten path and asked him. He told me exactly what was wrong. The thing would stumble and die and shut off. Of course as the heat rose while sitting it would fire back up again. It was actually blowing so hard there was snow coming in around the soft top doors. I put another exhaust manifold with a working heat riser and chimney on it and it was good to go.

    The 160 thermostat was pretty common for pre-smog motors. Operating temperatures were increased to reduce emissions, so that a 195 is now most common.

    You need to keep the engine temperature up enough so that the fuel remains vaporized on its way to the cylinders. You could try a 180 and see if that makes things work better. This will give you a little bit more gain in the temperature feedback loop too ... which might help to run closer to the set point. It'll also make your heater work better.
