Shame, but that is why you see so few on the roads now a days.
Got the derv going into a garage to look for a fuel leak on Thursday, checked all the easy stuff, injectors etc but it seems to be coming under the engine, might be the fuel pump. It needs the engine undercover plate to be removed and easier to get the garage to do it. So we will wait to see what is happening.
Good luck with it all, we will have to have a trip to Goodwood when you get it on track.
