The sector gear has to be shimmed so that it just clears the cut off lever but still meshes with the spur gear.You may have adjust the spur gear if possible to meet the needs of the sector gear.

Just keep using the same test technique and do the final test of screwing down the two shell and anticipating the difference between when the you are holding the shells together by hand and when the two halves are screwed down tightly.

Remember, too loose is always better than too tight.
