Thanks for everyones advise on my previous post (please help) but I gave up on it and sent it in to the shop (you have to draw the line somewhere) I got told to remove the sparkplug cap from the lead and see how far the spark would jump from the lead to the head (earth) apparently it should be blue and jump around 15 mm, well mine failed miserably only jumped 5 mm so it is most likely electrical I will keep you informed ( I hope it isnt going to cost too much!!!!!!) from Dave

 

I swallowed my pride,but I threw it back up.
