My 63 SF with a 70 400 and Edelbrock 1407 quit suddently, driving up hill in heat. I thought it might be empty tank, so rolled into station and it took only 13gal. then it wouldn't start, and somebody yelled "pump it" so i did. It started, and then backfired and burst into flame. Fortunately the air cleaner was off. A short shot of fire extinguisher put out the fire after 20sec or so. It then started and I drove home... So: the carb is covered in soot. Is it damaged? How to clean? Was this vapor lock? the rubber fuel hose was very hot, so i cooled it a bit with water. If so, is there external insulation for the fuel hose, to reduce vapor lock? thanks in advance for the help!
