here's my original story:
Here's the story:
tried replacing fuel filter, haven't done so in the car's entire life (my dad is the original owner, it's an L82 4spd. with 11k miles) so i figured it would be a good idea, when i was unscrewing the fuel filter inlet screw, the fuel line screw was stuck to the fuel line and it turned with the fuel line, the fuel line bent, and then snapped when i unbent it. We replaced the fuel line. In the process we stripped the fuel inlet screw threads inside the carburetor. We fixed that and then wrapped the inlet screw with teflon tape, put it all back together and started the car. The car started with a little trouble but the idle was EXTREMELY rough, and then it wouldn't idle at all. Right now, the car will not idle at all. When you press the gas while it is running, their is an extremely loud hiss and if you run it for more then a few seconds, the carburetor begins to smoke out of the smaller barrel that is closer to the front of the car and on the right hand side if you are looking at the engine from in front of the car (i know that isn't good). I can't determine what is wrong with the car.


here's some additional information i found out today:
Ok, today my dad came over and we looked at it together. Remember, when I was running it previously i was unable to see the engine only hear it. It is DEFINITELY getting plenty of gas...in fact it is flooding like a mother. When you turn the key gas floods in the carburetor so quickly that it is actually spilling all over the motor. The carburetor fills in a matter of seconds. What could be the cause of this?

 

Still sounds like you got some teflon tape or metal shavings caught up in the needle and seat assembly in the Q-Jet. The debris would not allow the needle to close off the fuel, like a stuck float. You might try GENTLY tapping the carb near the fuel inlet to try to dislodge any junk that might be caught up there.

Like I said in another post, I live in Hollywood, not too far from you, so if you need another set of hands or eyes, let me know.

 

i may take you up on that offer in the near future....what's your email address?

 

Gotta be real careful with those fuel lines. You need a 1" box wrench for the fitting and a 5/8" flare wrench for the line. Unscrew the line first holding the filter fitting with the 1" then unscrew the filter. Install in reverse.

It's quite common for a small piece of debris to enter the carb when the filter is changed, especially if you have a little dmage to the screw thread at the inlet. You most likely have a little piece of crap lodged under the needle. The only way you're going to get it out is to pop the top off the carb, remove the float, remove the needle, and clean it out really well. If you need some instructions on doing this, let me know, and I'll send you the step-by-step. Also, if you can't get it, I can do it for you and build you a new fuel line if you need it. Just throw the carb in the mail to me along with the mangled remains of your line, and I'll fix it all up.

 

There is an almost clear, thin gasket that is pressed on the back of the
fuel filter nut in the carburetor. It is what makes the seal between the
fuel filter nut and the body of the carburetor. During removal and
installation of the fuel filter, it is easy for this gasket to work loose and
become dislodged behind the fuel filter nut. This would cause leaking and
and a piece could become lodged in the needle and seat assembly.
The gaskets are available from any GM dealer and should be replaced when
the fuel filter is changed.
Also if the gasket becomes dislodged, you may overtighten the fuel filter nut
to try and stop the leaking only to strip the threads in the carburetor body.
(Don't ask how I know that)!

what did you do after you cross threaded the inlet? My inlet is cross threaded and I can't find anything big enough to rethread it....i can only find a 1/2" rethreading tool

 

Fortunately this was years ago and was not an original corvette carburetor so
I purchased a rebuilt unit and used mine as the core.
If if was an original matching carburetor I would send it to a carburetor
shop and have it repaired. I believe there is a helicoil that can be installed.
Do not purchase the oversize filter nuts available at some auto parts stores.
