Backfiring is caused by either the firing order being incorrect or the engine timing is incorrect. generally backfiring through the carburetor is caused by incorrect firing order. confirm the distributor is inserted properly and double check firing order beginning with cylinder number 1.

94gmc 2500 454 4wd backfires through carb while driving

could be a multitude of things. Firing back through the carb usually is caused buy timing issues. The distributor has a vacuum and a mechanical advance. If the advance is not properly functioning the engine will be low on power and may fire through the carb when accelerating.

1983 CJ-7 Had someone put water in gas tank? Blew out lines, rebuilt carb and cleaned out, cleaned tank, gas dryer and new fuel, new fuel filter (clear), new fuel pump,replaced rotor cap, plug wires,...

You put something back the wrong way.....any amount of water in the tank, carb or whatever WILL NOT cause the engine not to fire.....check any wiring/rewiring you did for accuracy

What is causing a back fire in the throttle body? My 93 safari wil run if pumping on the gas but dies as soon as u let off the pedal..

That is usually a timing problem but it could be the carburetor in need of a rebuild. If I remember correct GM was using Rochester Carbs on that model and they are notorious for this problem.

1992 olds cutlass ciera 2.5 ltr popping through the carb when you hit the gas pedal it popps or back fires throught the carb and you can see fire sometimes with the air cleaner off

I would make sure the firing order is correct. It is 1-3-4-2. If that's OK I would check for a valve train problem such as a worm camshaft.

Back fires thru carb, dies if i take foot off gas IF i get it to start

Sounds like a timing problem. Back firing through the carb usually indicates that the timing is after TDC instead of before TDC. Not running would be an indication of the same. The normal timing is just a few degree before TDC (BTDC).

2002 nissan 2753cc 6cyl firing order.

Carb.basic setting.
On the Carb to Intake manifold there is an AIR/FUEL volume control screw. Gently screw it in Clockwise until it bottoms out, then back it out 2 turns.
Next, find the Throttle Butterfly Fast/ Slow idling screw, and back it out until the Throttle linkage is released.
Then slowly wind it back in 2 turns
If you have SPARK and FUEL up, then it should Fire Up.
When it does, using the Air/Fuel screw to stabilise the idle mixture, adjust the Idling Speed Screw to run balanced at around 750 RPM.
All the best and Regards, DT
