Fire in the hole!!!!!!!!!

[stallion85]

Just put my Q-jet on today after rebuilding it. I changed nothing else, just rebuilt the carb and put it back on. Well I cranked her up and POOF a big fireball came out of the carb!!????!!!

What would have caused this? Luckily I have another rebuild kit, but am stumped to as what I did wrong

fill it up first...

You probably got a lean backfire when it finally got fuel into the bowls..its best to fill the bowls before firing it up by using a small peice of vacuum hose in the bowl vent in the center of the carb,and a funnel--or use a sqirt type dishwashing liquid bottle--it only takes about 1/2 pint,so dont dump in too much!..

Another option is to disable the HEI or unplug the coil wire if you have points,and spin it over for 20 seconds ,then hook it back up..by then the bowls will be full,and chances of backfiring is greatly reduced.. if you did something wrong during your rebuild,most likely you'll know it in the first minute its running!..

Cool thanks. I am going to try and fire it back up and see what it does.

I just don't want to burn the house down

Any singed eyebrows?? I have been a part of numerous fireballs out the carb. Helps keep ya on yer toes!!

Had flames come out of a dual quad tunnel ram once. It was dark outside and the flames joined above the carb. Scared the hell out of me but my friend sure thought it was cool.

Well, I was in the cab when the fire ball came out. I could see it through the crack in the hood when it was up. My wife and son got the hell scared out of them.

diesel4me- you were right on. I started it back up, let it warm up and tuned it in. She purrs like a kitten now


I was having a hesitation during throttle input before and now it is no longer evident. So mission accomplished
