Thanks sprocket, I found that diagram earlier. I am pretty confident I hooked everything up correctly. The machine sat for at least a year and I had the carb upsidedown at one point te get it out of the way while installing the new engine. So, pretty sure there is no fuel in float bowl. My question is, if there is no fuel in the float bowl, it won't start and create vacuum to open the fuel valve. So how does it get the initial fuel to start? Or, does it create enough vacuum to open the valve just with cranking? I will check for spark tomorrow. Yes, i have the kill switch in the "on" position.

Yes it will take some cranking to get the fuel to fill the bowl, you could first prime the carb, takes about 2 ozs of gas.

Cranking opens the petcock, starts fuel to flow.. but it isn't the fuel in the float bowl it is the old fuel in the gas tank that will plug the carb solid...pull the fuel hose off at the carb and see if you have fuel...when you crank the engine...

If there was old fuel anywhere in the tank or hoses then you need to drain the entire fuel system, flush it with fresh gas or carb cleaner, replace the fuel filter with one for a gravity feed and prime the float bowl... then you may have a change of getting it to start if you have spark...

The scooters runs and drives! Thanks guys!
Changed the stator, no spark. Took that all apart again, found no errors in my installation. Checked wires for continuity, found all okay. Began tracing other wires. Found the spade terminals for the coil where apparently manufactured from some kind of tin foil/lead alloy and had self-destructed when I slipped the protective boot over the coil. Repaired coil wires, had spark.
The scooter had sat for over a year without use and many had told me to remove and clean carb. Went to remove electric choke and it broke off with very little provocation. Must have been cracked during storage and moving from place to place. Contacted a guy I know who assembles scooters for local dealer who sells them and he had a spare choke. Went and got it and it was too big to fit in the hole. So, I ordered one from partforscooters.com. It was the same size as the other one that didn't fit. So, I carefully sanded down the first one (it was only about 1 mm too big) till it fit in the hole then ever so slightly deepened to groove for the O-ring with a moto-tool and used a very small amount of RTV in reassembly. It works and doesn't leak.
Scoots starts right up, idles nicely, power output seems fine, and everything except the fuel guage seems to work just fine. I put three miles on it going up and down my gravel driveway. (My motorcycle license expired long ago.) My driveway is half-mile long. Being on gravel, 30mph was as fast as I felt comfortable piloting this thing but it seems to work just fine.
Took me 3 weeks, but I got 'er done!
Thanks again and keep up the good work.

Oh yeah, I had drained all the old gas and put fresh in. For future reference, you can prime the carb simply by sucking on the VACUUM line to the petcock. Make SURE you are sucking on the vacuum line, NOT the fuel line.
I still had to briefly put my hand over the carb throat while cranking to get that first bit of gas in the carb passages.
