Ok. Here is the situation. I really appreciate all the help as I have no one around me to help out. I took the carb off of my 300u yesterday. Replaced the gaskets and float valve to stop a leak. put the carb back on. leak stopped but the engine revs too high. My tach is broken. So I don't know how high. I checked today to make sure that I properly attached the governor control to the carb. I was able to peek in at the throttle plate as my wife (lol) moved the throttle control. with the throttle closed, the plate closed, with the throttle open, the plate opened. All looked good. I put it all back together and... same thing. There are 2 possibilities in my mind. I will state them and you guys and gals can suggest whatever else.
1-somehow the governor is throwing the throttle open when it shouldn't. Not all the way... because I can rev the engine a little higher manually with the throttle control. (i do not know how I could have screwed this up by taking the carb off.)
2- When I took the carb apart there is one piece that I am unsure of its function. On the attached photo note the post sticking up toward the rear of the carb. This post inserts into a hole on the top of the carb in which there was a rubber.. something... washer... gasket... who knows. This piece is all but destroyed. The carb rebuild kit I got does not have this piece. What is this piece? Could it be causing my problems?
If not, is there a way I can figure out how I screwed my governor?

I've already drilled the center of the bolt out with about 7/64" drill bit the entire length of the bolt. Only one end of the bolt is visible. I tried to use an easy out but it wasn't budging and I didn't want t
