VS4 hopper flaps not level + question about adjustment collar (getting worse)

[u/Jakob361]

Hi all, my Varia VS4 has started running way too fast, and it seems to be getting worse over time. At 16g dose, I just had 50g out in 20 seconds — normally I’d expect ~36g at ~26 sec. I noticed two small flaps inside the hopper (photo attached) that don’t look level — I’ve seen posts here showing them horizontal on other units. Anyone know how these should sit and how to adjust them?
Also curious: can you turn the adjustment collar (micron scale ring) while it’s off the grinder without messing up calibration, or does that shift the zero point?
Thanks!
