The best way to set your work saw is to start out noticably "rich" and start making cuts. Lean it up and check the no load in between cuts for that distinct "4 stroking" sound. Continue to make cuts, when the saw cleans up immediately when a load is placed on it, and pulls hard thru the cut, you are nailing down the best mixture setting(s) that the saw likes.
Continue this procedure, when you don't notice any increase in performance in the cut, go back to the last setting, this will be a good place to be, regardless of where the no-load rpm's end up at. It is ALWAYS best to er on the rich side, than lean.
As mentioned previously, more fuel delivers more lubrication, lowers EGT's and no load rpm's when you come out of the cut. For a work saw, this will be best for the saw, and help it to last.
Also make sure, when making carb settings, that the saws air cleaner is clear of any debris, and that you are using fresh fuel mix.
Very small adjustments to the "H" screw may still be required, as there is less good air available on hot/humid summer days, compared to cool/cold "crisp" Winter days. If you notice at any point during the year, the engine revving high and not "four stroking" easily when the load is removed from it, add just tad bit more fuel ("H" screw turned slightly counter-clockwise)......Cliff
