1973 chevy c20 carburetor problems

Since replacing my header gaskets, my truck has been idling higher than it should be. when i tried to adjust the idle screws, i got it to what i wanted, and then realized the choke wasn't controlling the flap at all. now i'm replacing the carburetor, but the line that says filter than connects to the front of the carb won't come off. it's metal, and whenever i try to unscrew it, the pipe just starts warping. any help would be appreciated.

There is are special wrenchs used to remove the line, it is called of all things a line wrench, go figure. Any parts store should have the tools or you can buy it a Sears.

Your carb needs rebuilt, the float is to high or just really crapped up inside. You are dumping fuel in. Lee

I have a 1976 Chevy c20 pickup I am wondering if a intake manifold or a blown headgasket will make my not idol or run well can anyone help please


The simple answer is yes! To both! A blown head gasket will cause a lack of compression and either a black or white exhaust emmision. Improper intake manifold seal will cause rough idle or high idle.

Which end of the fuel filter goes in first on 1973 chevy nova 6 cylinder 250 cid engine


The filter should have an arrow on it. That is the direction the fuel flows. The arrow should point to the direction of your carburetor.

Hello and welcome to FixYa!

Just an insight regarding the problem. On cold start up, let it rev high till it reaches it's normal temperature, the idle will drop then when engine is warm so you can leave the breather adjustment screw in it's normal position.

If it still fails, then you can be facing vacuum leaks or there can be worn out vacuum hoses that needs replacement. If vacuum hoses are good then the problem can be on the carb itself. The gaskets can be worn out that's why you have irregularities on the carburetor's vacuum supply.

If that's the case. The carburetor gaskets must be replaced.

Hope this helps and thank you for using FixYa! Have a good one!

IDLE SLOW ON 2000 SILVERADO, 5.3 ENGINE, STALLS AT STOP LIGHTS, IDLES @ 500RPM. CAN IT BE ADJUSTED?


The idle is electronically adjusted by the ECM with the IAC (idle air control) valve which is located in the throttle body. Then the IAC get's to dirty from carbon build up, it can cause what your experiencing
Start with cleaning the throttle body, paying attention to the IAC passageway to try to clean the IAC. If this does not fix the issues, you may have to replace the IAC if it is to dirty to clean.
Thank you for using fixya and good luck, do not use carb cleaner, the carburetor cleaner is to corrosive to the gaskets used on the throttle body's. .
