As far as I know, a large percentage of "warm start issues" are caused by people not reading (or ignoring) the manual, and not performing it the correct way (with "fast idle" activated).
560XP, 562XP, 555, 545, 550XP etc. use computer programmed carburetors, no way to adjust anything, and 90% professional users.
I know very well what it is, and professionals often are more ignorant than informed non-pros + I don't believe the 90% number, but it may of course be correct in your area.

Also, I didn't mention any adjustment, just using the correct procedure, according to the manual.
