318 sb with a four barrel carb

Come to think of it, I'm not sure my choke was hooked up at the time since it was still summer and the car didn't have it wired when I bought it. I have the same AFB carb on mine, I turned my screws in till it bogged a little then backed them out a quarter to half I think when I did it. I've also gone by ear some. In particular when I was coasting down a hill in gear I would hear the exhaust popping. I had the same issue with my motorcycle and found out it was a lean idle thing. Backed the screws out another eighth to quarter I think and it's been running good since.
