Ever since I posted this thread a couple weeks ago I've been told everything from its normal and safe to I wouldn't fly it at all. For what it's worth, here are the results of replacing my old 10-3678-32 with a brand new billet machined 10-5217 from AvStarDirect.
I've had the plane back since Sat and have logged 9.3 hours on the new carb. Not only did the problem go away but it's like a completely new engine. The throttle response is way better, the idle is better, pulling the mixture to shutdown is a nice quick spin up and then it powers off, and she seems to burn less fuel. I know it hasn't been the same situation for everybody but my issue is completely solved.
