Hey, force carber here.
But, yes... I do get cloudy beer from time to time. I've gotten perfectly carbed beer in 8 hours (IMHO). Competition carb? No.
I chill first, cold crash which is normally part of the process anyhoo. What I do is start at 10psi, make sure I get a good seal, and rock. When the bubbling stops, move it up to 20. Rock some more. 25... rock.... done. Usually takes about 5 minutes max. Leave it at 25. If over night, purge in the morning.
I leave the CO2 port on the bottom so its always "bubbling". I do this before work, and come home, purged and drop pressure to pour pressure, and I have a decently carbed beer. Has never failed me.
It will clear up after a week.
