What is the clearance between flywheel and magnito?

I have a Briggs/Stratton 6.75 and I couldn't get it to start after several pulls, I primed it a few times and took out the spark plug it was not fouled but wet so I knew that it was getting gas; after a while I took it apart and found the magnito was gummed up I put the Magnito back but I did not use a feeler gauge, it has clearance but I would like to set it where it should be.
