Thanks!!

I am using D6F4-03 distributors with MSD 6A's on both a street and racing 240's. The distributor has a part called a 'contactor' sitting opposite the mag pickup on the plate in the distributor. No wires. I have searched this forum as well as Google with no definitive answer to the questions: What is its function? Is it necessary? How should it be positioned/adjusted? It doesn't appear to be magnetic as one post stated. Thanks in advance for the help.
