Idle/Carb problems

80ccstingray · Jun 27, 2012

Hi everyone! I have a RAW 80cc bike engine kit with a stock NT carburetor and it idles very fast and stalls randomly. I adjust the screw on the carb and it does nothing, it still idles fast. Can someone help me? Any ideas or suggestions are welcome.
-Thanks

First Thing does the throttle have and response at all.Then check for air leaks or the throttle barrel slide is in wrong in the carb.

Use a water spritzer bottle (with water) to spray around the carb to intake and intake to cylinder areas when checking for an air leak.(Engine running of course)

The gasket is notoriously bad. Also, though not as often the carb can draw air in through the top where it screws on.

I tightened the screws holding the bowl of the carburetor on and it runs better but now its leaking gas. Looks like ill be needing a new gasket.
Thanks everyone for your help!
