Back to the accelerator pump for a second: if you look at the picture attached (red arrow), there is NOT a port leading from the float bowl to the bottom of the accelerator pump like I've seen in many other 2G carbs online. The rebuild kit even included the check ball for this port (goes under the accelerator pump, in the bottom), but I noticed that there was not a port to plug. Only the port leaving the accelerator pump is there. So as a test, I left the air horn off of the carb and filled the float bowl with gas. Using the accelerator pump with my hand, I plunged it down and gas did go to the top side of the venturi port, past the check valve with the spring. But as I released the pump to rise, it did not get any gas back to the underside of the piston, as it had no way to get it. There is a slot in the accel.pump housing (at approximate 10 o'clock in the picture), but the piston does not rise above it to get gas under the piston.
All of this might not matter, but I found it odd that this carb was that much different than all of the ones that I see online. I wondered if it was a carb from a 'six-pack' config?? Somewhere I read that only one of the three in that configuration used an accel.pump, but I have no idea if that is correct. I don't even know if the tag on the carb is from that carb, as it was under a screw and could have been switched.
Any suggestions or comments are welcomed!!!

..."but the piston does not rise above it to get gas under the piston"...
Sounds like linkage (pump-linkage?) assembled incorrectly, as piston MUST rise above bottom of slot to allow fuel to re-fill the pump-well. And do NOT install a ball in bottom of pump well.
On some of those carbs and/or kits you have to adjust the float higher than the instruction sheet calls for--quite touchy and may require several attempts.
HTH,
