That is progress, at least. The focus now is on setting up the carburetor "by the book", especially the metering chamber. From my limited experience so far, as long as you have a matched set of parts, the main issue is the metering lever setting. However if you are planning to use a needle and a lever that do not match each other, I don't know how you would decide what the setting should be. It might be safer to find out why the needle is wrong, and what needle actually goes with the lever and diaphragm you are going to use.
