150cc scooter not running right

[micco]

Hi All,
my 150cc tomos nitro has been sitting for the last couple years from the pandemic - now looking to get it back on the road.

What's currently happening is any throttle and the engine bogs down, like its starving for fuel.
What i've done so far:
* removed the old gas from tank and carb
* cleaned main and pilot jet, all holes on main are visible nicely
* confirmed spark
* put in some newer gas
* checked valves, intake is at 0.003 and exhaust is at 0.004

I'm coming to the end of my knowledge, the carb needle doesn't seem adjustable, rather this is no clip but rather a washer - suspect i would need to stack them to raise, which i don't have.

It was running ok prior to being parked, other then I replaced the stator.

Any additional input/suggestions from the community would be appreciated.
thanks!
