Hi, Anonymous and the usual suspects are:
1. Severely drained or faulty battery.
2. Faulty regulator/rectifier or high output coil.
3. Faulty power valve, solenoid or installation.
4. Clogged air filter or exhaust.
5. Cracked or incorrect float level.
6. Float needle is not seating.
7. Faulty reed valve.

SOURCE: Hyosun Scooter Carb Adjustments
Very good thought process on the adjustments. The throttle screw sets the idle speed and the air screw sets the fuel mix at idle speed. The stock setting is 1.5 turns outward. IMPORTANT > do not tighten these two adjusters down. Only screw these in until they LIGHTLY seat. Now turn each adjuster one and one half turns outward.
From this point you adjust the idle speed then adjust the air screw for fastest idle speed at that throttle screw setting. If the idle speed becomes faster than desired after adjustment, just reset the throttle screw and then reset the air screw.
A “very helpful” rating for this answer? Thanks!

SOURCE: banshee wont rev
Usually related to TORS, specifically the safety switch in the clutch/park brake assembly. If it's defective the engine won't rev. Solution: look for a TORS removal kit.

Sounds like an air leak between the carb and cylinder. This would lean the fuel/air mix causing a lack of power on hills. It can also cause the bike to rev up by it's self on idle and flat surfaces. If the bike is not over 3 years old you should be able to tighten the manifold clamps and then tighten the manifold mount bolts. The rubber should still be soft enough to re-seal the connections. If over three years old the rubber seals and manifold connections are probably hard and cracked and will no longer seal properly. Just get new seals, gasket, and rubber manifold and you should be back in shape. If not, it is possible the crank seals are the problem. They can go bad and lean the mix. I mention the seals last because it is not an easy fix. I hope this helps.

PW have the stop\start\run switch and will not rev in the start position, there may be a problem in this switch, wire, or the ignition box which controlls this.
The small 50s can also build up carbon in the exhaust port, or the exit end of the muffler.
They also need the original air filter and cover (dont know why, but they wont rev without it).
I realize you may have checked some of these, but not much else goes wrong
