I have a 68 289 2 bbl that I recently got up and running and driving again. Anyway I rebuilt the carb and it still seems to me to be running rich. Idles nice and starts right up when cold but doesnt like to as much when it’s hot. The timing is good and shouldn’t be the issue. I ran the numbers on the carb it’s a c3af stamped round back carb with a 1.14 cast on it. 300cfm, and 51 or 61 jets. From what I can tell it came off a 1963 galaxie 289. Attached is a pic of a similar carb except without my manual choke. Under the diaphragm arm and cover looks different than the others I’ve see and just has a ball under the bolt coming from the top of the housing. From what I read there’s supposed to be a little buffer pad type thing. After looking at the diagram it’s the pump cavity filter. Could this be causing trouble as well? Thanks for any help, sorry if that was confusing.
