Do I need a new tank? Or is there a way tighten the stonefilter in place? It seems to move up, and down about a 1/4 inch.

Thanks Sean.

As for the Mugen clutch springs, there is a bad batch out there, and has been for a few months. I have read several different threads about broken Mugen Clutch Springs. I would p/u a different brand, as stay away from the Mugens for a few more months.
