Two days ago was the saddest day of my life, I cried for the first time in about a decade . On my way driving to pick my step-daughter up from school my cruiser started to backfire through the carb. Then stopped,...then right around the corner from the school did it again. Only this time the backfire ignited the air filter, which ignited the distributor, spark plug wires, electrical wiring, well you get the point. Luckily I do carry a fire extinguisher for these rare occasions. I have yet to find out what the total cost is going to be to fix it. Truthfully I don't really want to know, I know it's more than I can afford.
