My Series C Comet can tick over beautifully, but ...
sometimes, for no apparent reason, it speeds up. For some time, each time I slow down again, the tick over is at the higher speed then, for no apparent reason, it reverts to the slower tick over.
If I set tick over from the fast "version", then, when it slows it slows too far and the engine stalls. Of course, for safety and to allow me to stop at traffic lights without sounding like something from the airport, I set it to tick over when "fast".
I'm guessing this may be to do with the fuel level in the float chamber (new jets, needle, slide etc.). Sometimes when closing the throttle a little the engine picks up which usually suggests a slight richness.
Ideas?
