LOL, thats the problem right there. I had 1 fire on my 78. Daddy decided to spray starting fluid through my 60 dollar k&n air filter. Well the carb backfired and my nice new k&n went up in flames. Not only was the air filter hot, so was I. He only done it cause he couldnt reach the breather from the ground. I told him if we ever do it again we're taking the breather off.
