Is my turntable dead already?
Video will explain everything.
It could use a calibration but as long as it holds the pitch it’s fine.
you will rarely ever stop the platter from moving… If you’re scratching you shouldn’t press hard enough to stop the record it should always be turning.
Hmm..how could I calibrate it better?
It’s difficult to see in the video, but it LOOKS like the issue isn’t the platter at all, but the slipmat/needle.
If the slipmat is too slippy, it’ll take longer for friction to spin the record up to speed; likewise, if the needle is pressing too hard on the record, that’ll create additional friction which the slipmat has to work harder to overcome… by looking at the dots around the edge of the platter, it seems as though they’re both spinning at roughly the same speed.
Swap your slipmats over and see if the issue moves to the other deck, and if not then try moving the counterweight backwards on the tonearm (away from the pivot point).
I use butterugz, no slipmats.
I was told there is a a brake adjust hole with a ± marking to allow you to adjust the start and stop times of the platter with a screwdriver, but mine turntables have a “pitch adjust” and “DD speed”, should I rotate to the + at the DD speed to make it start/stop faster?
Butter rugs ARE slipmats 
!
DD speed (afaik) is the actual speed of the motor, so adjusting that will just set your calibration completely out of whack.
The fact you’re using butter rugs leads me to believe it’s most likely a needle pressure issue, as their main selling point is that the friction is SO low. You really need to look at the dots on the edge of the turntable rather than the record to determine whether it’s a TT/motor issue.
There’s some great vids on YouTube by this English Bloke who explains, in great detail, how to tune up your turntables. Somebody on here posted links to them a while back. Wish I still had the bookmarks.
What happens if you flip the record on the right? Same thing? Does the issue follow the turntable or the record itself?
We have the same turntables! Have you experienced this or no?
I haven’t experienced this but I only have 1 turntable so I don’t have a second to compare it to. Mine plays like the one on the left in the video. Seems like the torque is off on the one on the right.
Yeah..or something similar to that 
It really sucks because I use the one on the right to scratch with and it’s really annoying
Why don’t you just flip them then.
I suppose that’s an option but it still won’t go away then Guess I’ll have to do that.

That’s the guy. Thanks Smitten. He’s got some great info in those vids.
He knows his onions.
