    What do you guys think about a new carburetor for a '72? I rebuilt the quadrajet but the linkages are still rough & it still leaks a little gas. I was thinking about the Edelbrock direct quadrajet replacement, but the racing guys around her said to just go with the cheaper edelbrock & an adapter. This rig will be a daily driver with regular trips into the woods, so I don't need a racing carb.
    Thanks in advance,
    Brian

    Brian,

    Hey man....I already had a Performer RPM intake with a Carter carb on my 72 K5. The truck would not run right and gas leaked from everywhere on the carb. I put an edelbrock #1406 and so far its the best improvement I've made to the truck. It starts right up and runs great. No spitting during acceleration, no stumbling. Its awesome now, smooth idle...just awesome! I didnt expect that buying a new carb would make it run like a bran new engine but it did!

    The carb I got was $250 at O'Reilly. Go ahead and pick up an edelbrock performer intake also. Edelbrock has different performer intakes, one of them is for low end torque, get that one. I cant remember which one it is but Jegs has it listed if you have a catalog. You wont regret it!

    Later,
    David

    I would say go with the Edelbrock 1901 Q-qet replacement they work better off the road.

    Thanks for the reply. What is it that makes the q-jet replacement work better off road?

    The Q-qet carb works at extrem angles better than the updated carter AFB that the other edelbrock is. Ask crawlerfj40 he runs Sierra Off Road in Sonora and has good luck using the 1901 on off road trucks he's built. If you'll do a search on here for carbs the people that are running a good Q-qet tend to love them over other carbs off road.

    Heya,

    What about the off-road kit that edelbrock makes for their carbs? It's supposed to stop flooding during extreme angles. I havent bought it but its only $12.95 Check out this thread about it...

    K5 shuts off at an uphill or down hill angle

    Heya,

    I just looked at that 1901 q-jet carb over at Jegs. They look pretty cool. They look just like the stock carb. They cost more $392.99 compared to $250.00 tax and all that I paid for mine. I'm really happy with mine so far....I havent had it off-road yet though because I'm still building. If I have any problems I'll put that kit in...Ive heard good things about it.

    just four nuts to take off and put back on.then adjust the carb for your engine.and hook up a power wire to your choke from the ignition auxilary on the fusebox.also you need to cap off the right vaccuum port and put the left one to your distributor.

    chulisohombre,

    I meant putting the kit in the carb itself. I have a #1406 already. But which vacuum port did you use? The drivers or passengers side port?

    i didnt put in the kit myself.the previos owner did.its the only thing i think the guy did right on my truck.but i know it works because i switched carbs just to see what it would run like and it bogged when i hit bumps off road with the stock edelbrock or when i got the least bit sideways.

    Those Edelbrock Q-jets are rather pricy (as explained in this thread), and I have to say I'm pretty happy with my Edelbrock #1405 (manny choke) 95% of the time. It WILL stumble on the steepest angles however, so I will eventually purchase the offroad kit mentioned, which is supposedly a great fix. All-told, the #1405 carb and the kit are nearly $180 LESS than the #1901... which is good 'cuz I'm poor!

    They list remanufactured carbs on the Edelbrock site. Has anyone checked these out? They also have some list on the Jeg's site but only the 1906 in the Q-Jet style.

    I run the Edlebrock 1901 Q-Jet. I have ahd this carb sence 94-95ish. It has worked GREAT! I have never had an issue with it off or on the road. I just recintly rebuilt it and was a brease to do so! Great thing about the q-jet is once it is setup right you never have to tweek it down the road later on!
    Good Luck
