Could be just a carb adjustment required, the L screw on the carb will richen up the mixture, if increaseing the the idle screw does not help, try extra 1/4 turn out on the L screw, make sure the air filter is clean before makeing any adjustments.
its either you have to make sure there is spark, then check your fuel filter in the tank or on the inlet fuel line comin g from the fuel tank. there could b some condensation or dirt in the tank . U could also check the diaphram in the carburetor.
