    @stfuyufamf. To answer your question the saw ran good but as I get older Im looking for the most power in the lightest package. Echo is intent on pleasing the EPA which means they set all of their engines on the very edge of lean. The carb needs to be enriched, and the muffler needs to have another small vent added. Beyond that its port and piston work.
