There is so much that comes into play today on setting a carb.. Possibly even having to pull the limit caps to properly tune.. And putting them back on of course.. Most dealers send their techs to school to learn how to do just that.. As well as other things depending on the level of service the dealer chooses.. As for most saws without a limited ignition they have a max rpm setting that they will set with a tach, hopefully under for a couple of tanks then have you bring it back in for a retune..
Good techs that can hear a saw 4 stroke and have a piece of wood to run the saw in can teach you what to listen for by burying the saw in a piece of wood and letting up to hear it clean up in the cut then 4 stroke as they let up..
Once your learn to hear what four stroking is vs running away lean you will cringe when you hear people with a box store saw and a dull chain...
Some of these new saws turn over 14,000 rpm out of the box... Not much room for error with those kind of rpm's...
