Hello, I am just starting a leak down test and discovered leaks at the carb joint.  After I dissembled the block, I found a gasket between the joint and reed assembly that's not supposed to be there!  The diagram shows the only gasket is between the reed block and the cylinder.  I'll leave the gasket out, but is it OK to smear a light coat of sealant there just in case?  I see there are sealing ridges in the joint surface, but after 50 years, they may have flattened?  
Thanks All,
