Puff Out Through Carb During Starting (Video)

Hi folks I am getting a puff of smoke out of the carb when trying to start car. Here's a short video of what is happening.

The Long details: I just rewired the engine and charging circuit. I pulled the distributor and primed the pump since the car has not been started in awhile. I put everything back together exactly as it was since I marked the distributor and gear. I added a couple gallons of gas to the tank. I took out the plugs and let the starter turn the engine over until fuel got to the carb. Put the plugs back in and it fired up and ran great holding a steady 21 inches on the vacuum gauge. I let run for about 20 minutes it got up to it's usual 195 running temp. The engine ran great just like before I started the wiring project. The volts at the battery was 14volts and the voltage drop was .3 volts measured from the positive terminal to the voltage regulator ground. Everything seemed perfect. I shut it down.

About ten minutes later I went to start it back up and it turned over several times then started pulsing smoke out of the carb. I pulled the plugs and everything looked normal. I let it cool down for a few hours with the plugs out then put them back in and tried to start it. It would turn over several times then pulse smoke out of the carb.

I pulled the valve covers and turned the engine over without spark to make sure all of the rockers and valves are going up and down. They did. I then checked to make sure the rotor was pointing at #1 when at around TDC on that cylinder. It was.

Any thoughts?

Thanks in advance
