help i have tried every thing i have a spark some times it is good when i kick it over then it goes weak . i have cleaned the electrical sockets but still does not improve , when it does start it runs for about 30 seconds and dies. i have replaced spark plug and changed the coil also the battery,it seems like an electrical fault have you any ideas.
