Joe,
For timing the industry standard for needlebar rise from BDC is .093mm. At this point the tip of the hook is just barely behind the needle and usually in the middle of the scarf when set at straight stitch and center needle position.
The hook timing is always set before the needle height. Then it will be easy the gauge the height for the needlebar.

I've got several clones, over a half dozen, and they are not the same. Some work good and some are cranky, but no two are exactly the same.
Some have timing marks and some don't. But even with those that have timing marks, when the timing marks are lined up the needle points are not in the same place relative to the hook point.
