bobbin not suppose to go around??hook is the one picking up the thread,the one that goes around.by turning the handwheel towards you,after removing bobbin and needle plate to get a better view,notice the position off the hook in relation to the needle eye.if timing is correct the hook point should be just above the needle eye on the upwards stroke off needle bar.if your hook is turning anticlock when handwheel is turned,needle should be set at far left position to check timing and if hook turn clockwise set needle to far right.if thread gets picked up when sewing straight but not getting picked up on zig zag,it mean the timing still little bit out.if hook does not move when handwheel is turned it mean hook gear or belt is gone.basic height for needle bar on top dead centre is approx. 5mm between needle clamp and machine body or needle approx. 5mm from center of hook/bobbincase when lowered bottom dead center.good luck!!
