Rochester QuadraJet Rebuild Kit

[Pesimist]

Well, after 25-years of faithful service its time to rebuild the Carburetor on my Volvo AQ205 (GM 4.3).

Does anyone have a source for rebuild kits (gasket sets)? Carburetor is a Volvo PN: 856138, Rochester PN: 17088142

Accelerator pump quit working last summer.

And....Which phase of the moon and alignment of the planets will be best for ensuring no left over parts?

Here appears to be a kit including the accelerator pump.

As for the star alignment, it's snowing here so can't see them

Anyone else? The ebay source didn't have rebuild kits for the AQ205. Carburetor is a Volvo PN: 856138, Rochester PN: 17088142

Top of the forum, the "Boat Motor Parts" link."Volvo Penta Parts"Link.
Open that and find the Sierra parts link. It should have the Volvo/Quadrajet parts.
Sierra 18-7072 Amazon about 13$

That's an excellent carb. If you've never re-built one, you may want to take it off and bring it in...... I've heard they can be a little finicking to tune, that's why I believe they got a bad rap and people called them Q-junks. If you know a mechanic that has worked on a lot of Q-jets, that would be a plus...

Agreed they are fickle but when done right there the bomb so to speak. With that said unless your very experienced it's probably time for a new one..you need to check every moving part for slop or wear..the throttle blades and the shaft blades screw's ect. With that said due to age i would soak the carb in vinegar for 7/12 hours followed by a bath/dip in a baking soda that will neutralize the acid. Make sure you do a complete disassembly of the carb includeing the power valve you want the vinegar to dissolve matter in the circuts..Good luck they can be a hard nut to crack.

Nothing wrong with Q-jets.
It's probably to your benefit to have it done by a pro.

What is meant by "Hard to tune"?
How about the needed manifold gasket part number?
