I still dont follow. The two holes on the sides of pulley plate are places for transit screws it seems.

Hello

I am quite new to  turntables.

I got myself used Project Debut III and it works nicely and I really enjoy it.

But as I change the speed manually from 33 to 45 or other way around I usually encounter this problem that as i put the vinyl on the platter it does not sit smoothly and if I turn the turntable on, the record visibly wobble. I have no idea why is this. Sometimes I get it right and many times not. Like now I'm stuck with vinyl not leveling on the platter. I am not sure if it is because of the subplatter problem or the upper platter problem or something else. Could someone assist me with the problem, please. I really would appreciate help and guidance.
