Hello Cheryl,
I am trying to remember your exact model and the drop feed mechanism, all these drop feed switches are very simple and usually it just means a slight adjustment underneath the switch which just contains a raised spring, if it is possible for you to e-mail a picture of underneath the drop feed dial I can see exactly what adjustment needs to be done and it will be very minor, answer only on my e-mail address because I don't go back to questions to answer on howtomendit.
