 It is a necessity to play with the AFM with cams of large duration.
My experience was that my motor would not idle at all until I 
adjusted the AFM. 
   To get at the spring take a hobby knife and cut around the black 
plastic. You will see some type of glue around the edge between the 
metal and the plastic and this is what you should cut. You can then 
pry the cover off and adjust the spring . One direction is rich and 
the other leaner.
   Good luck.
