I've never had a little saw that I couldn't tune good enough and close enough on the bench or on the tailgate until now. I never would have thought. I've got a little Echo CS-306 that has the CAT punched out and that could be part of the issue not having its normal back pressure. I'm going for a little Scout outing this weekend and there's sure to be some trimming and campfire duty to be done so I got it out to dust it off the other day and it just didn't respond right. It's been sitting bone dry so it's not stale fuel. I tried adjusting the H needle and it just wouldn't clean up and under load it would falter. Either way, dropped it into a log and tuned it in the cut and there we are, right as rain.
I've experienced this issue with other saws that have Muff-Mod or neadly open mufflers like on the old classics but never on one so compact, they just seem to keep on purring.
