cheers for all the advice, sorry for the delay in reporting the out come but I have been working onsite at Glastonbury. anyway, I replaced the fuel filter bleed and non return valve and the copper injector washers . cleaned up the looms and connections on the starter motor. she is now starting like a dream. she doesn't cut out when idling.
however I now need to sort out a host of new problems.
oil leak from transfer box, oil leak from rear axle/prop, pulsing noise coming from ACE system and change rear springs.
cheers again. anybody live in N.Devon?

Sounds good-think there are some pasty munchers just over the border in Cornwall

cool, I am not far from the border.
