Rochester 2bbl carb Problems, wont idle down

Ever since ive had my regal, ive had problems with the carb. It got better after i replaced hoses, checked for leaks and replaced the primary pulloff.

Its the E2ME version, electrical 2bbl version.

The problem i have is, no matter what season or temperature..
I crank the car up and it imediately idles extremely high, i have to sometimes tap it down. Then it'll slowly idle back up extremely high to where i cant leave it warming up by itself. I have to continuously tap the gas at a certain time to get it to proper idle. Or else i'll be driving down the street with my foot on the brakes full force and burning gas like crazy.

So basically its not idling down by itself when it should.

Is this a problem with the electric choke thermostat? Or somthing else like a float bowl issue? Maybe the secondary pulloff?

I hate it because it takes longer to tap it down during winter and i just dont feel like putting up with it anymore.

OH, and after the cars been drivin all day, turned off.. go back out and crank it up it idles fine, so its something to do with temperature in the engine and carb.

THANKS for any help!


EDIT: other things i took off are the sensor on the air cleaner and the valve thingie at the end of air cleaner hole (with the hose coming out), and i lost the aluminum or metal ducting connecting exhaust manifold and air cleaner assembly.

Try looking for a screw on a semi circular steped piece connected to the choke.I would unfasten it and take it from there.

Your choke needs to be adjusted.
