This in response to post about stylist 457 that bobbin is not moving. I have the same problem. I changed the small gear and moved the timing belt but can't figure out about the timing. I notice the circular cap under the machine and hook doesn't seem to have screws in in it. I'd appreciate understanding the way to check the timing hook connection. Thanks, Seanne
