Fire breathing Carb!!

This wasn't nearly as bad, or entertaining as my first backfire, where I perfect orb of fire shot out of the one barrel on the inline six of my old Mav. Of course I was leaned over it working the throttle, and lost some hair.

 

Lesson learned.
Back in high school one of my classmates was firing up a 350 Pontiac on a stand after a rebuild. He leaned over the engine to hit the throttle cause it wouldnt fire. It backfired bigtime and blew the air cleaner lid off and smoked him right in the face. Guess he should have put on the wing nut and timed it right. Damn funny.

 

That's WAAAAY more funny. I usually don't have the air cleaner on when I'm doing stuff like that, since it gets in the way. Now I have a whole new reason.

 

I lost an eyebrow to a lean backfire once...once...

 

had same prolblem for 2 months. did plugs,rotor,distributor & cap,plug cables,wiring harness.and still ran rough getin worse with time. had to keep timing really high or keep foot on gas. starting to burn really rich. then yesterday.got off freeway and yup. timing chain and cam wer worn down.timing chain loosened up to point where it would flood out at idle and blow flames out the carb. if you did all the other timing stuff check timing chain or gear like he recomended.
