you need to check to see if it has a spark at the plug ,make sure it has fuel in it and the right fuel,check the compression .check the plug first take it out and put the ht cap back on it ,then earth it on the side of the head and spin the engine over on the button and see if it sparks.these are fitted with an immobiliser so if thats playing up it will not spark.
