check if spaark plug is alright by removing it but leaving the the ht lead on and turning the engin over . if it sparks then that is alright .. if it is not that then there is probably no fuel getting to the carb so remove air filter and pour a small amount of petrol directaly in to the carb and try to fire her up if she starts and runs for a few seconds then you will know that fuel is not getting to the engin .
