I have Carb rebuild parts from Cliff Ruggles , But havent had time to finish building a core I have. To frickin busy with many other projects, been sitting for over a year

Is anyone running a JET Performance Rochester Quadrajet.
STAGE 1 - Disassembled, cleaned and inspected to restore factory stock performance. Casting plugs are sealed with epoxy to prevent leak-down. All of the circuits are checked for proper sizing and the calibration is checked for proper jets, primary metering rods and secondary metering rods. Quadrajet Carb is reassembled with new float, choke pull-off and bronze bushed throttle shafts.
Show More
STAGE 2 - All features of Stage 1 carbs plus fully recalibrated idle, off idle, main, accelerator pump and high speed circuits. Provides improved idle quality, instant throttle response and maximum torque and hp.

Have you had good luck or issues?

ALL carbs are made in China and they have a very limited life span, on purpose.

Go get a 4000 series real AFB

As a guy who has worked many q-jets, I would strongly suggest not buying one that hasn't been tailored to your engine.
If you knew what you were talking about, You'd know you can get one that is "tailored to your engine". And they are modified with adjustable power piston for further adjustment

Maybe you should get Cliff Ruggle's book and do some studying

I’m no real help but I thought I’d post that my qjet was built by Sean Murphy Induction which was supposed to be a group of former Jet employees, SMI closed a couple of years ago.

That said, I sent my core to SMI and requested a Stage 2 rebuild. I had to fill out a questionnaire detailing my engine and truck so it was built to spec for my application. I’m happy with it and it runs really good, I only needed to make the typical minor adjustments when I installed it.

I bought and ran a JET 35002 stage 2 carb that I bought back in 2014. I ran it for a few months and it did well on the street but wasn't good for going up or down extreme hills nor at slow climbing at 10,000'+ So I removed it and went to fuel injection that happened to be better suited for how I was using my truck.

35% off because of black week at Jet carbs. Do a close visual inspection and if everything looks good give it a try.
