well i went to start my blazer and it backfired through the carb and started a fire /forums/images/graemlins/angryfire.gif i jumped out popped the hood took the air-cleaner off and had big flames /forums/images/graemlins/shocked.gif so i grabbed my jacket and tried to smother it nope didn't work /forums/images/graemlins/frown.gif so i was cursing myself for not replacing my fire extinguisher /forums/images/graemlins/frown.gif and trying to think of where i could get some water fast. then i spot-ed my half case of pepsi still in my truck from last weekends snow run. i grabbed one and poured it around my carb but not in it. all those flames went out so it was only coming out of the carb. so i then smothered it with my jacket and got it all out /forums/images/graemlins/smile.gif it did melt my air cleaner though and my throttle cable /forums/images/graemlins/shocked.gif but i did get it started and drove it home /forums/images/graemlins/smile.gif now to find out why it backfired through the carb?
