    Hi sure you know this but if it has worked and now doesn't and you have done nothing its most likely to be electrical check your coil solanoid kick or electric start and check colour of fuel and any blockages in the fuel lines if it starts but stalls go through the troubleshooting in your Haynes manual and check through them fault finding can be a night made but just persist
