Ok, this is getting weird now. I remade the earth and started it from cold, now it revs to just under 2k and sits there. If I disconnect the idle speed control valve the tick over speed does not change. I have buzzed out the wires to it, they are fine. before it ran out of fuel it was perfect, it has not run properly since.
Just as a sanity check let me run this by you. When the fuel ran out it spat back quite violently- I think I saw a blue flash somewhere round the inlet manifold. Could it be that the backfire has taken out the inlet gasket and I now have an air leak? I don't want to take the manifold off if it's a completely stupid idea but something changed at the point I got that backfire - it has not ticked over properly since. The gasket is actually that instant stuff, I could not find a proper gasket for it, I am hoping I don't have to scrape it all off.
Can someone tell me if I am completely barking mad or not?
Would an air leak cause a high / erratic tick over?
Thanks in advance
