Hi there guys!

First of all, can you quantify the statement above?
We need more info to offer solutions that might be cheaper and easier than replacing the carb.

I mean, that there are many reasons why fuel is not delivered to the carb.
1/ Insufficient fuel in the tank. Dont believe the gauge!
2/ Blocked tank vent, or loss of pump prime due to a cracked supply pipe.
3/ Rear electric fuel pump is missing/broken/electrical supply failed.
4/ Blocked fuel filter... FYI, my '84 345 has 3 inline. One by the rear electric pump, one on the chassis rail by the step, one on top of the intake, and one inside the carb!
5/ Failed mechanical fuel pump.
6/ Failed float valve inlet, or float stuck.
7/ Blocked internal passage in carb.

Now, if the Carb is old, aged and worn out that is a reason to replace it, but #1 thru 5 are not the carbs fault!

Should a carb be on your list, and I am going thru this at the moment, despite the fact I rebuilt mine, I am not happy/secure I did it right, as its still running odd.

I have selected my Guru, Cliff Ruggles of Cliffs Performance.
He is building my Carb as I wrote this.

He has the has the reputation, and literally wrote the book on Quadrajets!

i get fuel flow all the way to the inlet of the carburator, I dont see any fuel spray so I think the bowl is stuck. i havent open up the carb but if I pour raw gasoline into the primary the engine runs for a few moments...I may add that the MOHO havmt been running for 2 years.

Got it!

Not sure how mechanical you guys are, so you will have to update us.
Replacing the float and inlet needle is not that hard, but can be tricky...
Removing the top of the carb its easy to drop screws down the intake, which is a world of hurt!
Best to do it on the bench, which is where I did mine..
Here is my carb, top removed.
Float is square black thing between smaller chokes.
Inlet needle is far right center.


Here is a tip that might get things moving...
The float is right below a hole in the top of the carb between the 4 chokes...
If its stuck, and not allowing fuel into the carb, it is in the "Up" position.
Putting a small long screwdriver down that hole, and gently pushing the float down might unstick it.

I ordered a rebuilt carb for my 460 from Carburetor Exchange at www.carb-x.com last year. I bolted it on, adjusted the choke and have enjoyed it ever since.

I really love Quadra-jets and they are simple to fix. The only reason I'd ever get a different one is if something like the throttle shaft holes are worn too much! If the float is stuck just rap the side and top of the carb with a wooden handle of a tool or gently push the float down as suggested above. I have seen the rubber tip of the float needle get stuck in the seat a few times! Despite being a Luddite if I was in a position to need to replace a carburetor I would buy a Holley throttle body replacement fuel injection system because gasoline is a different substance now than when Quadra-jets were made. It might pay for itself if you drive enough miles! You can figure the price of a different carb as a discount off the spendy price of the fuel injection.

Good advice!
I would put an aftermarket EFI on my rig in a heartbeat if CA smog would allow it!

I have to admit I don't know for sure but I thought '80's trucks over 3/4 ton are smog exempt? At any rate I'd think Holley has a certification from the CARB to allow the cleaner fuel injection system to be used? That might make too much sense though.

Back when I had my 77 Argosy I did a carb swap and regretted it. Unless you get a replacement that is the EXACT replacement for your original, it will not work as well as the original.
Unless the numbers match perfectly, the jets and ports may not be the same. The linkage can be different, and on and on.
Often a rebuilt carb from Joe blow auto parts will not be a good remanufactured unit.
If you are unsure of your skills or just want to be sure it is done right, send it off to a Qjet specialist. It will take a month and it may cost 2 to 3 times as much, but the results will be worth it.
Of course that said, on my 84 Excella, I ripped out the Qjet and installed a TBI kit, and after I worked the bugs out, it was worth it.

Not sure about CA, but in NY the age and vehicle type exempt you from the emissions BS, I bet my emissions are better now than with the Qjet. If you have a buddy out of state with easier rules, register it there
