Carb stuck open?

[RRoriginals]

For the past three weeks my car has been in my driveway, starving to get on the road again.

There's an apparent vacuum leak, but I checked all my hoses, tightened up all bolts.

My first thought: Valve cover gaskets - Fixed.

Took off my air cleaner to diagnose it, but it seems like my carb stays stuck open, so more air than fuel is getting to the engine. Would this cause a high whistle, followed by stalling out? If you hold your foot on the gas it'll stay running, but once you release it the whistle/chirp gets louder and the car finally shakes to a stop.

try starting it up and spray some carb cleaner around the carb and hoses and is the moter revs up you've found you leak..

Going to have to wait for a friend to come over for that, not able to start the car and keep it running on my own from outside lol.

But I did notice that when my throttle linkage is set, the carb is closed; when you start the car and hit the gas, the carb opens up and stays open, never closing again until you manually close it.

Are you talking about the the plate at the very top of the carb is closed at first then it opens when the car starts up and stays open? If so, that's the choke plate and it's supposed to do that.

The choke plate is open 24/7, If it was supposed to stay open 24/7 I don't see a reason why it would be there.

it should close when the motor is cold and open once it warms up..
you never metioned what car you had.. maybe the car has a choke cable and the cable is stuck...

Exactly why I said, it shouldn't be there if it stays open. But would that cause stalling issues, on top of a whistling/high pitched whine?

So bringing this one back from the dead...

2bbl on a 383. Bone-*** stock.

Fired her up a couple of weeks ago, and she ran fine. Fired her up today, and at idle the carb is whistling Dixie-quite loud and high-pitched. Thought it was the belts at first, but I narrowed it down to the carb. Lubricated all the carb linkage and she still whistles. Give her a little go-go juice, and it shuts up.

Suggestions Gents?

This is an old one!

I use a spray or squirt bottle of water around the carb base. It will change rpm if there's a vacuum leak. Check if the carb hold down studs are tight. Carb base gasket, pcv hose, ect.
