Rebuilt top end of engine now carb idles much higher?Please help

Jimjimjimmy thank you for the heads up about the ends of the valley pan. I wasn’t aware of that. Why doesn’t it matter about the ends of the valley pan? I tried to use the keyway that allowed the bottom gear to line up properly based on the dots. I didn’t remove the keyway when I installed the new lower gear.
Lemondana what is a throttle bracket and how would it help me?
