, and when the ferrule is tightened, I have no drips, no cross threads, and most of all no bad mouthing my old carb. I do need to take care of some trash in the gas, but that has nothing to do with the repair job. Also, at the same time, I put the new inserts in the carb flange from McMasters-Carr that have been mentioned here. All in all, it is a professional job of repairs that should last a long, long time. 
Just thought I'd heap the accolades on the right person when they are so well deserved.

BTW, Thanks to Daniel H. who posted about the inserts and told me how to install them the easy way.
Good on you S.S..
When I tore the carb back apart, I could find nothing (trash wise) to make the needle valve stick and make it run over like it did. So, I took the float back off, and the needle valve didn't come out of the seat like it should. I removed it with needle nosed pliers, and ran it between my fingers. This is when I noticed a sticky feel to the needle valve. A quick washing in the sink along with the carb top helped solve that problem. After letting it dry and putting the parts back together, I remounted the carb on the Cub. It fired right up the first time, and I readjusted the idle. I can now pull the governor control almost to the full rear, and the Cub still runs, though at a very low rpm. Still no leaks, and no complaints from here!
