At the top rear passenger side of the carb there is a setscrew locking a spring adjustment that goes to the vacuum butterfly on the sceondary. the spring is only adjustable 1 turn. A slotted screwdriver is used to turn the spring adjuster after you loosen the Allen screw.

The back of my Rochester quadrajet carburetor the 4 barrels dont open when at full throttle what could be the issue its a 1984 rochester on a olds 307.?
Quadrajets have a maximum airflow of from 750-800 cfm. Because the secondary side of the carb opens according to the airflow requirements of the engine, the same carburetor size can be used on a large range of engine sizes. The basic 750 cfm quadrajet casting is used from 231 CID to over 400 CID - the big secondary air valves open only as the engine breathes. For example, on a mild 350 Chevy the air valve will never open all the way - because the motor can't use more than 600 cfm or so. Your 307 will simply not require the full use of the secondary air valves, at no cost of engine power however. -DB, 1969 Hugger Orange Camaro
How does quadrajet secondary jet air valve work?
As the accelerator is depressed with load on the engine: such as being in gear, engine speed will begin to increase. As the engine begins to require more air and fuel, the secondary air valve will begin to open. These valves are controlled by a choke pulloff vacuum canister which releases as vacuum in the intake drops. Then the suction of the engine will allow your air valves to open also causing fuel to be sucked into the engine through the secondaries. When these valves open, a cam that they are mounted to will lift the secondary metering rods higher out of the jets which allows fuel to pass more readily through the carburetor and into your engine. Cool sound!

To adjust the choke on a 1978 350 4 barrel Chevy truck engine, turn the screw on the side of the carburetor. This screw is located in the side of the carburetor. Turning the screw to the right makes the choke open farther. Turn to the left to make the choke open less.

They only open on demand, Higher RPM. There is an excellent reference book available that can be very helpful when fine tuning. I believe it is called "How to rebuild and modify a Rochester quadrajet". This book should be a part of every carb rebuilder's toolbox.

Why the CT secondary short circuited?
Current transformers produce a ratio of primary current in the secondary. If the secondary of a CT is open circuited, and primary current is flowing, the CT will try to push that same ratio of current through the secondary open circuit. This causes secondary voltage to climb until it the secondary open circuit flashes over. This can often damage the CT.

Have you checked to see if the float has a hole in it allowing fuel to weight it down? Possibly the needle valve is sticking and not the float. Could also be the float needs adjusting. You need to open the carburetor up and see what is going on.
