I just bought a 2018 Bintelli Sprint 49cc. Did not run when I go it. New Carburetor, intake manifold/Gasket. Valves adjusted and starts right up. Scooter will idle fine and rev up quickly with no issues ,except when I rev the engine it stays high and takes a while to come back down. Sometimes it will come back down sooner than other times. Sometimes if I rev the engine again it will drop back down quickly.
I have tried adjusting A/F, valve adjustment, vac hose inspection. Engine is QMB139
