    Tried many of my NRV tools to remove a very stuck NRV in a nickel AL-1947 Primus 96 I finally received yesterday. Thought in a photo it might be nickel A little kero down the pump tube and in the tank did not do much after a few hours, I'm impatient anyway. Worried I might crush the fount around the pump tube. I had been toying with placing the fount in the jaws of my vise, but it was just barely too small. I looked at the possibilities of a vise more and realized I could place the stove fount just beneath the jaws and would have plenty of room with one of my shorter tools to fit, with the fount wedged between the jaws. I placed some leather gloves around the fount to protect it and finally felt what I thought was that satisfying snap. Unfortunately, I now had a leak after trying two different NRV's. I was trying to avoid any solder work. Was the leak from the torque to the part that holds the NRV or did I push in the fount by the pump tube and loosen that area? Luckily, just heating up the area where the leak was sealed it up. I could not heat the area enough to get my solder to flow, but could see the factory solder getting shiny. I had peened the burner earlier as I had fired the stove yesterday but had the leak out the NRV, so thought I would fix the flame. Runs great.

    Thank you John. Wish the '15 which works was as nice, that one needs a master to take apart and reassemble.
