    Yes seemed like more fuel efficiency, no gap setting required on 4 electode plugs and seemed like easier starting

    Forget it! I have a Perma Green Ultra. In fall, I used an expensive "Split Fire" plug with an electrode that was split so that it was like a snake tongue. But...I found myself starting with the rope instead of electric starter most of the time. One day motor started to miss badly--stalled and would not restart. I could not roll the machine up the ramp and back on the carrier on the back of my truck. Some guys from another company helped me. A few minutes later I found a used Champion plug in my toolbox. Installed it and PG started immediately. R12yc or something like that.
    I suspect that if you have two electrodes you are just getting two weak sparks, instead one one strong spark.

    i have seen adds for plugs that show bolts of electricity jumping from those plugs 2 and 4 ways at the same time. we know that eletricity will take the least resisted path. it won't divide equally and fire at all points. to me it will fire across one point. the advantage of platinum plugs is the electrode doesn't erode near as fast as a regular plug. Just my thoughts......
