I can't remember but I'll check my book tomorrow and let you know if no one jumps in with the correct answer. Rick.

Re: rich lean setting

start at about 1.5 turns. start the motor and let it warm up. at idle turn the knob in until it begins to stumble or cough. then back it out until it just smooths out.
