REFLECTOR: Franklin engine rear seal.

Several Franklin owners on this list have had this leak.  Mike Deter found that the leak was not
around the shaft, but the outer edge where the seal fits in the crankcase.  I fixed mine by using
high temp silicone sealant around the rear side without removing the seal, just the metal ring that
holds the seal in place.  Replacing the seal is not too dificult so long as you use the correct
procedure for getting the seal over the shaft end which is twice the size.
