if its going back on your stock MH rebuild stock, but for performance get a bunch of # drill bits, bunch of jets, rods, sec jets, and start drilling on your lathe, no aftermarket help for jets or bigger seats, i got the one in the pic working good but the 750 holley carb with annular boosters was still better.

why hasn't anybody suggested the Edelbrock? i keep one in my shed i fit up to cars that run like bags of ch!t, just to prove it's a carb fault. i bought a strip kit for mine but it just works so well as it came stock. they're almost a T/quad in their design & just like the T/quad, no gaskets below the fuel line.
That's one that I was asking about also in my origional post also, a friend of mine put a Edelbrock on his 340 Cuda and love's it,,,took a little to get it tuned in, but once we hit the sweet spot then

If it sit's more than a week you have to prime the carb with gas to start it, no amount of pumping the accelerator give's it enough gas to start,, act's like the bowl's are completely dry,,,won't go into 4 barrel mode when pedal is slammed to the floor, run's on 2 barrel only,,,idle adjustment screw's have no effect on idle quality,,,and it is just a scuzzy, scurvey, nasty looking mess,,I just want to make sure all is good and ready to go with the best economy that I can get from this barge. 
Doesn't sound like 'Thermoquad only' carb-problems to me. More just a neglect of maintainance 
The "no-4bbl" mode sounds like a simple linkage adjustment could fix easily, or maybe the sec. airvalve spring is adjusted too tightly. Does the kickdown function OK?
Idle screws, perhaps the fuel passages are blocked with dirt or something, or there's a vacuum problem somewhere.
The 'empty' carb priming is something more cars have and can be fixed by installing a simple fuelpump near the fueltank.
Adding a thicker heat insulating spacer under the carb could help aswell.
If you decide you want another carb, I would personally go with an Edelbrock carb.

Mega-DITTOS to SOME of what HermO said ..... 'cept that Eddy carb ... That is a stone-age carb compared to the TQ. You want FUEL ECON ? .... stick with the TQ. Get an older FACTORY service manual .... good info and tips in there. PLUS ....go to Napa and get a set of brass floats. Those plastic floats(using the alky-blended fuels) ...are NOT the plan.

All of his symptoms, with the exception of no secondary operation, can be traced directly to leaking wells in the bottom of the float bowl. Break out the JB weld an it'll be fine.

Any one ever heard of Southern Carb's and rc hobby in Jackson Mississippi?,,,looked up Thermoquad's on E-Bay and they came up as a supplier,,,98% posative feedback.  seem's to be reasonable on their pricing for complete rebuild's.

239.00 for the one listed, and a 6 month warranty.I have your # wrote down in my little book of important people to know.
Is that a rebuild or exchange? I can definately beat that price..........And, I can get it back to ya in a couple of days. Oh, I`m not THAT important....
That is a buy now.
