I have a 1974 Caprice Classic and I have replaced the fuel filter and did a tune up and yes replacing the distributor cap and rotor as well oil change and tranny was just rebuilt in October of this year so I know the filter and stuff was good there. My problem is the idle is rough and the longer the car runs the more gas you smell along with a burnt smell. It will spit and sputter and try to die. What would be my best bet to start with replacing now?

 

Rebuild the carb and reset the ignition timing.

 

Thank you will try that! Feeling hopeful!!!
