How good is your eye sight? The needle needs to be almost touching the hook as it gets to the top of the eye of the needle. You loosen the hook and move it right to left and/or forward and backward so that you achieve the hook hitting the top of the eye when the needle is on its way up, and almost touching the needle. The BlockRockit (and most longarms) is one of the simplest machines to time -- no feed dog timing.
