Hello Tedtractor,
Just wanted to make sure you get it, as you have asked for the instructions.
Your model engine idle speed is set @ 2000 rpm's. To adjust it you simply use the idle screw.
If you need to adjust the air to fuel mix ratio, here is how to for an aluminum head.
Adjust the idle speed to 1750 rpm's, then carefully pry the mixture adjusting screw plastic cap-limiter.
While watching the tack, turn the mixture screw both ways until the engine starts to loose rpm's.
Hold the idle lever while turning the mixture screw, that way you will maintain the idle you just set at 1750 rpm's. the half way point of the number of turn is where you set the mixture screw.
Put the plastic cover back on with the stop tang 1/2 way between the stops. return the engine to 2200rpm's. You can adjust the air to fuel ratio with the rpm's @ 2200, but that would be too rich, because the higher speed would require more fuel-richer setting. Let me know if you need more help,
Guido.
