Jim,
You should have used a Winfield SR-CC-D which has an accelerator pump to eliminate the flat spot after idle.
Winfield S carburetors did not have the accelerator pump.
The pump was at the bottom of the float bowl and vacuum actuated.
The amount of fuel squirted was also adjustable with a needle valve at the top of the float bowl.
