They are really thin and soft. Take a 1/8" bit and drill VERY carefully only through the thin top, then take a hook pick and pull the cap out. really easy. Don't be surprised the adjusting screws are stuck in there. try not to break the tangs off, it then becomes a process to remove the brass screws. after 50 years the original cork material around the brass adjusting screw becomes like concrete.

Be careful with those screws. If your carbs are very old and the cork gasket are hardened, you will break the brass screw. Then you are in trouble. I remove lots of those in carb restoration. First I remove the hardened gasket with a pick. I now have a lathe so I’ll make a special tool to clean them out faster, but a needle pick will work. You may need to soak it first in wd40 or carb cleaner. So the cork gasket is the only issue ? And once you get that out the screw usually is free? Or do the threads need to be lubed up too ? I have an old set and am getting ready to flog them.

If you look at the bottom of some baseplates right where the idle screw goes in it sure looks like holley dimpled the base after the idle screw was set to lock it. Rumor has it that that really sticks them in there, I think drilling those would help relieve pressure. Soaking, lube and a small sleeve that fits over the idle screw so one side does not break off will lead to success.

Thanks to everyone for the replies. Do the gaskets need to be replaced after they are removed? If you mean the cork gasket around the needle, then yes. They come out dried up and in pieces. It’s the same gasket as the center metering block screws.

If me I would work with the idle fuel feed restriction, 383 pulls fuel different than the 440 even using same cam. Ends carbs have no squirters so it has to be richened up a little in that restriction, like you said it idles good and moving the needle let’s air and fuel in, you only need fuel.
