It's stalling-out when idled, it'll let me use it pretty indefinitely it seems. I've got other 2-strokes that bog-down and stall-out when idling (opening the choke a little usually keeps them going, doesn't seem to help my chainsaw though), however my like-new chainsaw (I got it under a month ago brand-new) was stalling-out today after about 20min of moderately-heavy usage, it'd stall-out when idling but would let me rev it & use it, it's just that letting off the throttle fully would begin a ~10sec degradation of engine-power to the point of stalling!
I've seen this in other equipment but my chainsaw was exhibiting something odd alongside this - when I'd go to re-start it, for whatever reason it'd be spinning the chain (w/o me touching the throttle) in idle, quite quickly actually, and stay at that position until I manually touch the throttle, then the second I'd let go of it it would return to the 10sec-til-death routine. I started it, watched the chain go too-fast til I tapped the throttle, then watched it take ~10-13sec to calmly choke-out, maybe 5 times before giving up on it...
Any advice for whether this is more-likely Idle or L adjustment would be greatly appreciated!! The filter isn't clogged at all, there's ample bar&chain oil (and I've got it set to really throw the stuff so it's lubed for sure!), new chain moves smoothly, ethanol free fuel with synthetic oil @sharp 40.0:1 with Stabil added...saw is an off-brand, "scheppach" brand 25cc unit, stated 11k rpm (I've got a tachometer on its way in the mail but nothing here..thing works great and was un-stallable the first ~10x I used it :/ )
