A couple real easy mods will make it run even better. Get rid of the top baffle on the muff but keep the USDA spark arrestor screen and pull the limiter caps and tune it a bit and then replace the caps. Echo from the factory sets them a tad rich.
All mine and ones that come in that started to score were all set lean from echo too.My experience with several Echo saws, over many years now, is that they're set lean from the factory. I have yet to come across one set rich.
Just buy a new one and get it over with. You can afford itm saws are chump cgabge compared to tractors, new pickup trucks and large implements.I almost picked up a 661C with a 36” bar last week. Sent money and found it was a scam or an idiot. Luckily I was able to get money back.
