Bad to worse, now it won't start

OK, so the sick little scooter saga continues.
Down from the high of my previous post, now my Spree won't start.
Here's the scoop:
It ran fairly well, but was a tad hard to start sometimes, and it seemed like it was idleing slow.
I tried to adjust idle and air screws as per technical manual, and didn't have much luck. In fact, I made it worse, so that it would start, and idle fine, but as soon as I gave her gas, she would bog and die.
So, the answer to everything in these forums seems to be "clean the carb". I followed the carb-cleaning instructions in the technical documents step by step, ensuring that a good clean squirt of carb cleaner went through (and came out of) every hole. I made sure I could see light through the main jet.
Reassembled the carb, set the air and idle screws as per instructions. I know that my petcock is stuck open, so no need to apply vacuum and fill the bowl. I did remove the bowl drain, to make sure that gas was flowing into the carb. It was, and I replaced the drain.
Now it doesn't start. I pulled the spark plug, and checked for a strong spark. The plug was not wet, so no flooding. The spark was strong. While the plug was out, I used a compression tester and tested the compression in my new engine. 130psi, so it's high and needs decarbonizing, but I would prefer to save that for a maintenance job once the engine is running. But obviously no need to think about rings or piston damage with compression like that.
Airbox is tight, filter is installed, I don't have screw for the middle, but that's covered with tape for now.
I'm stuck here: everything seems right, but it just won't start. I don't see how a carb cleaning can make it go from starting to not starting.
Any thoughts?
Thanks guys!
