Asked by Bryan Dec 30, 2016 at 11:53 AM about the 1984 Chevrolet C/K 10 Scottsdale LB 4WD

Question type: Maintenance & Repair

So I put this reman quadrajet 4bbl on my 305. I can get it to idle good in park
but as soon as it goes in gear, it runs rough. So I adjusted the fast idle up to
compensate but now when i cut the truck off, it will diesel on me. I checked my
vacuum hoses and they are good and connected correctly. What am i missing
here?

Who rebuilt your Quadrajet? They are tricky to work on and not the greatest carb. I would have got a replacement such as Edelbrock or similar.

I bought a reman from national carburetor. I have been fiddling with the fuel air mixture some. I think I am going to pick up a vacuum gage and give it another go tonight.

I agree and disagree with Bob. Qjets are more complicated than other carbs and need a Qjet knowledgable repear guy. Don't go aftermarket. Get hold of Carbjunkys.com. They know how to fix a Qjet.
