I wonder if I loosen the fast idle screw if that will help to lower the fast idle cam when I tap the gas.  Currently the fast idle cam is at 1700 rpm.

Did you check/adjust the choke rod length?

I haven't made any changes to the choke coil rod.  I disassembled the carb and had the stripped fuel inlet threads repaired.  After cleaning the carb I put in new gaskets.  There was no problem with how the carb ran on fast idle before the rebuild.  Perhaps I used a thicker carb to manifold gasket.  I'm not sure.  Before adjusting the rod I'm going to try and loosed the fast idle screw.  It should reduce fast idle rpm but it may also allow the fast idle cam to fall more readily.
