Opening and cleaning the AFM didn't help my intermit loss of speed, mileage, rough idle problem. I did it as per archives.  Some people mention moving the "track" the lever follows.  To accomplish his, does one move the baseplate or the arm itself.  It seems there are 3 screws holding that base plate on.  I assume I am to loosen these and push the plate barely closer to the arm.  Is this correct? 
Thanks for a simple yes or clarification if you have done this.
