    I don’t know the initial settings but seem to remember something about the low speed needle actually being more of an air bleed…. So, adjusting is opposite to conventional methods…Turning the needle in/clockwise reduces the amount of air and richens the idle mixture, backing the needle out allows more air and leans the mixture…The high speed needle adjusts in the conventional manor. I’m sure someone will correct me if I am wrong, but something to consider.
