Good advice from amps, check the mix in a different environment.
Also, it’s possible to have two track that are synced too well and you get phase cancellation on the kicks, causing them to sound hollow and a bit off. A slight drag on the platter to nudge them off time should fix that quickly though. I
If the center hole of the record is a bit too big/loose, that can cause the tempo wobble; that’s easily fixed with a bit of folded paper jammed in.
Vinyl is finicky, that’s why I find those mixes way more interesting to listen to. Perfect is boring.
