My 50cc Scooter has a brand new carb but gas is leaking from overflow ???

You may need to adjust the fuel/air ratio. There is a small screw under the pull starter facing horizontally (its behind the plastic air filter cover, but accessable) adjust either clockwise or counter clockwise in small increments and give it gas and see if it dies or boggs down. Also check that spark plug is clean and not fouled, and air filter is clean and olied.

• Do you see spark? If not, check the side stand kill switch. It kills the engine so that you don’t start out with the side stand down. If broken or out of adjustment, it would kill the spark. Check for a broken wire at the side stand switch and coupler. Try moving the side stand kill switch by hand. If that doesn’t work then wire a jumper around the switch to bypass it.
• Is the handlebar kill switch on? Is it shorted out?
• Check the fuses.
• Check the operation of the ignition switch and all kill switches with a volt ohmmeter. Check the wiring harness. Did a wire come unplugged? Are all wires clean and with solid connections? Any abraded or pinched wires?
• Is the bike in neutral and the neutral light is lit up? If no neutral light, check the neutral switch and neutral switch wire on center or side casing.
• If still no spark, get CDI system and coils checked at the dealers shop.

SOURCE: Fuel is leaking from the

the floats in the bottom of the carb need resetting to the right place

you need to set them so that when you lift the float the fuel stops bent the bracket where the pivot pin is "BUT BE CAREFULL AS IT SNAPS EASIERLY"

hope this helps

It requires three main things to start the scooter:--- 1)Gas. 2) Spark. 3) Cylinder compression.---------- Any of the one is not functioning right so scooter is not starting.------------ Its possible that gas is not flowing till the carb and that is causing the problem.Either gas valve is clogged or faulty.Or gas line is clogged or carb itself is dirty and gunked up inside and needs to be cleaned.--------- Click this link below and follow the troubleshooting :--- http://whatisbyme.blogspot.com/2011/08/lifan-50cc-scooter-not-starting.html ----------- This will help.Thanks.Helpmech.
