GARY F Posted November 27, 2021 Share Posted November 27, 2021 I have a 37 Olds 8 cyl. When i bought it the carb was in parts and I sent it away to a pro to have it rebuilt. today I put it on the manifold, hooked up the auto. choke and when I looked at the carb where the two idle adjusting screws are in between the two screws is a threaded hole. I have all the service books on the car but does not show anything about this hole. This stuff was all apart when I got the car. Do you know what this hole is for? It looks like a small line would go here like the choke line is. Thanks in advance Link to comment Share on other sites More sharing options...
