Hi Grumpy, got myself a new diaphragm yesterday after a long drive ( that's the only problem with living out in the sticks with no suppliers around, 200kay drive, lucky the missus wanted to do shopping as well or it would of had to wait another week ). Put new diaphragm on, got to excited and almost forgot the spring, had to take apart again and fit it, second pull kicked over and now purrs like a kitten idling and on full revs.
Thanks everyone for your help, much appreciated, Paul.
