Make sure you hold back the starting threads, or at least the top thread, for about three stitches. Ensure that the needle isn't too small. Move up a size or two to see if that helps bring the top thread up into the leather. Choose the correct size needle for the thread combination.

Do standard troubleshooting stuff. Start by checking the hook to needle timing. Adjust the hook or needle bar height if it has been thrown out by the impact of sewing rubber. Remove the throat plate and clean off any residue on the bottom of it. Also, check the feed dog and clean it if necessary. Re-time the machine. Change the needle to a leather point needle. Make sure you've threaded it correctly and that the top thread stays inside the tension disks and doesn't lift up as you sew. Center the check spring if it was turned to one end or the other end. Finally, make sure that there is a modicum of tension on the bobbin thread; not too much or too little.
