No no no guys. Sorry, but don't bring too big a hammer. If you have a symptom like described, don't take a drill right away. And if it's a lean situation, drilling bleeds will lean out further. Or changing them, I've never had a carb I couldn't get to run fine, even without ever changing/drilling any bleeds
pantera74Bills6976, first make sure your idle circuits are properly adjusted. Then check your power valve, on cars that don't drive much they easily harden, and then they can be both too lean and rich. If all those are OK, try richening the main jets.
