Bill,
I would order a new compensator spring from Starbolt or Hit and Miss. A 
spring too stiff will make the mixture too rich and impossible to set 
the mix right. Eliminate that variable with the new spring. Then you are 
down to check valve and mixture control. How does the taper on the 
needle valve look?
