I found this dirty 500 at a yard sale. I want a "user" for deep frying fish and general camp duties. (They can't all sit on the shelf) It ran, but weakly. Electrolysis cleaned up the burner, and I gave it a coat of VHT ceramic header paint. I left the grate bare metal. Fashioned a windscreen out of a "meat and cheese tray" bottom. Currently it's running on 66% Kero 33% white gas and it seems to like it. I'll try a richer blend as I burn up the fuel in the tank. The knob is not original. Overall I'm pretty pleased.
