Update, I adjusted and cleaned Mee-mee's sync screws. From what I can tell, they touch, but his behavior hasn't changed at all?

Yeah so I gave in and peeled Mee-mee, and at first I was overjoyed to see that in my first peeled test run, the sync screws didn't really touch. I tightened and cleaned them with an alcohol prep just to be safe, assuming that would be the end of my struggles, but after 3 more test runs with slight adjustments to each run, he's still acting the same way he did when I first unboxed him. Though, for run #2 he froze after 3 loops and had some of that evil bugged out audio I talked about in my last post. Any ideas?
