Hello all. I hope that everyone had a happy Thanksgiving. I am having a problem with my lp gas 450 that has me baffled. I rebuilt the Ensign regulator/vaporizer and it worked great. I ran it bush-hogging for several days, on and off, no problems whatsoever, although on cold mornings I sometimes had to "prime" it with gasoline, because I thought that I might have the idle setting not quite right on the vaporizer, but I wasn"t sure how to adjust it, so I just let it be for now. About a week ago, I was running it, bush-hogging, and it starts to misfire, and it acted like it wasn"t getting fuel. It began missing more and more, and got to where it sounded like an old JD 2-cylinder, and I finally parked it til I could find out the problem. Well, it wouldn"t start even with it primed, and I finally determined that it has no ignition fire at all. I set the points at .022, had the condenser tested, it is good, replaced the coil from my JD that ran, and it didn"t do the Farmall any good, checked the plugs, they all look fine, checked to make sure that I had full voltage at the coil/ external resistor, still no fire at the plugs. The wires are old, but I don"t see how they could be that bad all of a sudden. Any suggestions would be welcome. Thanks, Hugh
