Anyway got housing off, put on bench, then spotted it, the central pin in the stat which the bits slide up and down on had come out, and was now jammed against the "bridge" piece where it was to start with crimped around the middle section, so pushed pin back in, then reinserted it where it should go, got it in the vice corner and crimped it properly, works perfect again now, never seen that in 25 years before though, it has FRANCE and COLSTAT written on it.
Might be somethging to watch out for, hate to think of one jamming closed, it also seems to have killed my IK31 plugs with it being too rich, grabbed another set out the box, but they were IK24, found some IK27 which should do, beleive this is what NMS use, 31's seem a bit cold and foul too easy, anyone else have this problem.
thanks
