Thanks for that Tony. Some good stuff there, even though I guessed some of the more simple stuff, there is a lot a funny little things I never realised (use of a fuel delivery valve to stop pressure reflections for example)... and it's nice to know for sure about the stuff I guessed about! Still trying to get to grips with the run-off from the injector - is this fuel that has leaked between the needle valve and the tube it sits in? If so why do relatively recent engines seem to leak quite a bit of fuel back, surely modern manufacturing can produce a good seal while allowing movement? Just thinking about it - maybe it's only a small amount each firing, but with so many firings per minute it could add up quickly with 4 cylinder engine? Also while I understand it's unlikely, I have a SR3 which is I believe one of the engines prone to possible runaway from diesel in the sump, and so I'll ask the question: What about using the compression levers to control a runaway? I assume it could damage the valves, but that would be the least of your problems in such a case. Hope you don't mind me asking, but it's your own fault! :-) Cheers, Mike -- Michael Askin http://shoestring_DOT_zapto_DOT_org/
