Are you sure the timing has gone,?
Check these first, needle in the correct way round, threaded properly, needle not blunt or bent.
If the machine still misses stitches arfter checking this then it needs retiming, select straight stitch, take off the needle plate, take out the bobbin case if you have a seperate bobbin case, and undo the two clips to take off the race cover, if you have a drop in bobbin just take out the bobbin, take the bottom off the machine so you can see underneath the raceway, tilt the machine back it will be easier, turn the balance wheel by hand towards you so the needle is going down into the machine then on its way back up, just as it starts to go up stop, look at the point of the hook, it should be just above the eye of the needle, if it is not undo the screws on the vertical gear underneath the raceway and you can move the hook round to where it should be, tighten and put the plate and parts back and test sew, if you have a front loading bobbin case undo the screws on the shaft of the raceway and move the hook round to where it should be, it may take you several attempts, if the machine sews perfectly on straight stitch test it on wide zig zag, if it misses stitches one side you will have to start again moving the hook either side slightly until you get it right thx nick
