RE: engine wont start
Its best to start with the carb, pull it apart and clean the fine mesh filter inside, I find it at times causes the engine not to fire, plus check the needles and spark plug. Try not to flood if it doesnt start, if you do kick it over a few times to get rid of the excess fuel, then try starting it again. There are lots of things to check so start with one and work your way around.....
