You might also run a bit of crocus cloth over the needle valve. They sometimes get a bit of corrosion on them. If you're running a fuel tank that you're not absolutely sure of, there may be a buncha junk in it that can end up in the carb.
It's real simple to pull the airhorn off an Eddie. Just make sure that you're careful when you remove the 3 spring clips, cuz they can end up in another zip code real easy. Then remove the screws holding the airhorn on and pull it stright up. Be careful when putting it back on...the metering rods have to fit into the jets and more than one guy has bent them. So don't force it.
You should have a good running carb when you're thru.
