you have to take carb apart you will see a plastic float that pushes the cut out valve up n down , were it touches the valve theres a little metal tab u ajust it there,
by bending it but be gentle and a tiny bit at a time

CARB PROBLEM

post a cameraphone picture of where the carb is leaking from on here so we can see.

did you take the float off the bottom of the carb,
you may have put it back on upside down.

Hi can anyone please tell me how to remove the tyre off the front wheel? I have a slow puncture as the rubber around the valve has perished.
Thanks, Will.

Hi is there any chance you could kindly send me your guide on how to change the main jet on a Baotian BT50QT-9. I am thinking of upgrading to a number 85 main jet.
Regards,
Will.

hey, here's my guide

Remove seat (2 10mm nuts on top and 2 10mm nuts in the seat and one screw at the front)

loosen the pipe going into the carb from the airbox/airfilter

loosen the pipe going from the carb going to the engine

pull off both pipes

unscrew flat head underneith the carb and put the pipe near it into your fuel tank and blow into the one on the top DO NOT GET THIS THE WRONG WAY ROuND or risk a mouth full of petrol

unscrew all 5 screws from the under side of the carb

u'll see a brass screw with a hole in it near the middle ish unscrew this

and put the new one in

rebuild

tilt bike to the left for 1 min

start

enjoy

The top box should have a bracket that takes it past the fuel cap, you have to take of the l.e.d brake light and the bracket fits into the holes that are left, hope this helps, also a 50cc should not go above 30mph anyway, my advise is to leave it at that, especially for a 16 year old. Put it this way come off at 30, cuts and bruises, come of at 50 . . . .. well ill leave it to your imagination
