low idle??

[jmitch333]

Once again, Ive run into another problem with my 76 c10. I thought replacing the fuel filter would fix this problem but it didnt. The truck doesnt want to idle right. Itll idle low and then stall. This happens in gear and in neutral. It runs fine on the road its just when its at a complete stop and I let off the gas. It idles fine if I barely give it gas. I looked for an idle adjusting screw but couldnt find one. My truck has a 250 straight six one barrel carb 3 speed on the floor setup. Any suggestions?? Thanks in advance.
