Problems with my 50cc taotao scooter

[afrance9191]

I bought a used scooter and it had sat for 2 years. I glt it home and drained gas tank, put in new fuel and fuel filter. Sprayed carb cleaner in it. It starts fine but when riding it bogs down real bad. It has a vacuum line that is missing but i do t think it shoukd be causing this much trouble. Any help?

If you hear a hissing noise when the scooter is running from the junction where the missing hose connects then you got trouble. A hole of any size in the intake system will cripple your engine. Been there.
