I have a 1966 Ford galaxie 500 with the 390 2bbl carburator. I'll give you all the details I can. So first off, I bought the car and a few weeks after owning it, the engine bursts up in flames. And after that, about 2 weeks later, it catches on fire again. After that, I rebuilt the carburator, new plug wires, new plugs new distributor cap. Once I did all of that, I didn't have any issues really. Then last Friday, i start it up and I smell a familiar smell (burning) so i put it in reverse and halfway floor it out of the garage, once out I pop the hood and sure enough the temp gauge wires were burnt on top (can't be the temp gauge wires cause there ground wires), but there was no fire. The carb dosent leak any gas anymore so I dont know what's causing these fires? At this point I get a new coil just to see what happens, well that's where the new problems start. Now it dosent want to run with the choke plate open all the way, it has to be about halfway open, otherwise it will run real rough. Also idle has to be high otherwise it will run rough. When engine is running it runs rougher, and rpms fluctuate quite a bit. Also I notice at night that I can see a blueish colored flash of light around all of the spark plugs when they go off, and sometimes I see a blueish flash of light on the coil wire where it rests on the metal. I put the old coil back on hoping it all goes back to the way it was, but no it still runs terribly. This is my daily driver and I can barely drive it now. Please HELP!!! Sorry about the long post, any help is GREATLY appreciated!
