sticking float
Take the carb off shake it REALLY hard, or take the bowl off and clean it all really well.

turn the carb upside down ,and blow through the gas line to see if it is shutting the fuel off completely- if not the needle might be worne out, check the tip for grooves
check the float height if possible go to eb@y, and you can get a owners manual
dont forget to clean the little pilot jet, and most likely you will need a new set of reeds, i cant remember what year is interchangeable -
as i have the 81 kx 420,and needed them you probly will to
clean the silencer ,and repack it-
IF YOU HAVE THE ORIGINAL DONT THROUGH IT AWAY!!!
find a way to fix it its very rare
i still havent found one stock for mine in 17 years of owning it
clean the air filter as well-
