Hi mate, first check the state of charge of the battery, if the lights are dim or non-existent then it probably needs charging. if its 2-3 years old anyway, you probably need a new one by now. Also take spark plug out, clean it & check the gap. Won't be anything wrong with the petrol after only 3 weeks.
