Hello im new here i know a little about scooters from one i previously owned. I just bought this jonway 50cc scooter. It was sitting in a garage for three months. When i first looked at it i had to charge the battery then the scooter was idling fine. I tried to test drive it when i noticed halfway through the throttle it would bog out/cut out etc cough basically. Now i cant get the scooter to idle. Theres also a little bit of gas leaking out of the air filter box. Ive been thinking of doing these things in the morning.
-Checking the lines for leaks
-draining the fuel to see if somethings in there.
-cleaning the carb
What i need is help or some tips. I've never had these problems so its all new territory for me.

Good advice from tortoiseIf fuel is leaking out the airbox, you definitely should check the carb's float needle, it could have been gummed up by the sitting fuel, allowing fuel to constantly flow in when running. |

I agree and the no run issue makes me think gummed up carb as well

Not knowing your experience or scooter history/modifications . . . To establish a troubleshooting baseline . . always a good idea to check valve clearance . . inspect intake manifold, insulator, and O-rings for vacuum deficiencies . . and perform a cylinder compression test (10mm spark plug adapter required). Keep in mind that cold fuel does not atomize/combust well. Expect some bogging until engine heat warms up the carb bowl fuel. |

Thanks for all the help everyones so helpful  My experience is mostly panels, fuel lines, gas tank, etc the basic stuff. I've never really dug deep into carb/engine stuff because i never had to. Im one of those guys that fixes it as it breaks instead of randomly just digging into it to see how it works. I'm going to wait till payday thursday so i can make sure i have the tools ready. If i cant fix it ill either buy a new carb and put it on or suck it up and take it to one of the local shops. |

Dig into that carb and clean it all up and try before buying a new one. It's fun and you learn. |
