I don't know which one of you is worse, Regor for asking or Mech for answering. What now ? are you going to wander in there with a screwdriver and adjust it ?
Regor,
You shouldn't be performing any maintenance on any a/c without the M.M.
I have access to the 320 MM and have just had a look, there are very specific figures for "throttle lever load measure". I'm not even going to give you the figures because I don't know the effectivity of your a/c.
If for no other reason, other than covering your own @r5e, not to mention being a bit professional, always refer to the MM.
The reference you require is 76-11-17-400-041 F (Adjustment of the Artificial Feel Unit)
