You need fuel,air and a spark for your motor to run.First determine if you have a spark or fuel,this will half yourproblem,if there is no spark then its an ignition fault and if the plugs are not getting wet then its a fuel problem.Start from the plugs and work back keep me posted ok.Check for spark first just remove a plug and fit it on the lead hold the plus to earth[with an insulated pliers to prevent a shock]get a buddy to swing her over and observe for a spark at theplug contacts.
