    Could be a mis-alignment between the motor mount and stuffing tube, or a cheap stock collet with a lot of runout. If those check out, you can pull the liner forwards, clean it with some alcohol, put a few wraps of teflon tape around the end, then slide it back in. The teflon tape creates an interference fit, so you may need more or less to get the desired result.

        The twisted flex has a lay for CCW props that climb upward towards the motor collet which acts on the teflon and pulls it upward.

            it means it's either poorly machined out of center or fits poorly on the motor shaft. Both visible as a wobble when spinning.
