Re: drive gear nut?
Do you remember in the film "Sabrina" the moment when William Holden realizes who Aubrey Hepburn is?

YES! Thank you! When I was trying to fit a standard socket, I tried my regular spark plug socket, and it was of coursew too large. So I never after thought of the kit socket.
EUREKA! It works!
