I checked the throttle plates and they are almost completely closed. It is a new carb from Quick fuel I purchased last year. Mechanical secondaries, 4 corner mixture screws and front and rear idle adjustments. My car doesn't seem to develope much vacumn so I installed a 2.5 power valve. Also there are no holes in the blades. After changing the air bleeds and adjusting the idle down I had to loosen the throttle cable and allow it move forward because it was holding the throttle open a little.

So you have physically looked at the idle transfer slots (from the bottom of the carb) to make sure they look like a "square"? What is your idle vacuum and at what RPM? Float level is where? Sounds like you recently replaced the PV. Have you checked your plugs to see how they look?

I suppose it MAY want more initial timing at idle, Have you tried adding more timing? Just trying to work through possible issues.
