Hi, again, thanks for the advice. You have thrown me by telling me to go in the opposite way with the idle needle (Rich). But what you say makes sense.

One question, is it possible to have the slow running idle set too lean and the engine keeps going??? What would you expect the syptoms to be??.

When I open up the engine the syptoms are best described by it seeming to take a deep breath and then go flat out, absolutley no mid range.
