Thats how I used to do them. Bought a can of Berrymans and disassembled every piece. But didn't have a can of cleaner and thought I got it good enough but it still has the occasional sputter. Back when I was doing a couple carbs a month I had all that stuff. I did tear this one completely down but can get into the fuel passages. And I have even done throttle shafts and butterflies in the past to replace worn shaft bushings. This one didn't need thatYou've got a lot more cleaning to do beyond that. And, the entire Carb needs to be disassembled. The only thing that doesn't get taken apart is the throttle shafts and butterflies. Soak the pieces in Carb cleaner (get the gallon can with a basket in it from NAPA) at least over night.... All of that gasket material must be removed to metal. It needs to be surgically clean and laid out on a white towel for assembly. My OCD talking....
