i have a 1985 4x4 Carbed 22r pickup. About 4 months ago it started to idle rough and act like it wasnt running on all the cylinders. i thought it might be a air/fuel mix prob, so i had a spare carb so i tossed it on and it ran better than ever until saterday morning when i was heading on to shift at the firehouse when i got on the gas to pass a semi and it backpopped and started to run just like it did 4 months ago... speratic idle, dies if no gas... is soemthing clogging my carb?



any help would be excellent!

Thanks in advance

I wonder if you can swap in a fuel injection system. Fuel injection is 100 times more reliable than a carburetor. I know this would be a lot more expensive, but you would have a lot less trouble in the long run. You could have a clogged fuel filter. I'd change that and run some cleaner through the gas tank. Both those carburetors probably just need a rebuild.

thats a good idea but i need to fix this first i think... i need to get to the firehouse =)

i think its a vacuum leak or something to do with that... its just he low and thats terrible. High rpm's is fine

no one has a clue?

Check the egr, air filter, vaccum lines etc.. Systematically go through the simple things check the distr., cap, rotor and wires.

Also try the fuel filter.

was a vaccum hose. thanks
