I just got a new MS261cm and noticed a smell the first time starting it.. and subsequent times its still there.. I thought it might be a "new saw smell" but its been too long... Ive got 2 tanks through it and I know chains tighten when they get cold etc but something just doesn't seem right...(yes chain brake has been released). I shouldn't have to loosen the chain prior to each use should I? After use it prob has a little more sag then perfect and its oiling correctly as far as i can tell...The chain does loosen up after a couple revs but something is def holding it back until the chain gets spinning... I dont want to cook the new saw... I have a 25 yo ms170c (since new) and 2 husky 455 ranchers (10 years) and have never seen this...Could this be a chain brake issue or stuck clutch or am i just being a paranoid new daddy?
New ms261cm chain usually tight when cold

Yes, you should check the chain before each use. Tighten or loosen or leave as is, as necessary. I check for sag as an first indicator, but the final check is -- does it rotate easily?
Yes I check the chain before each use...So far in the dozen or so cold starts-- it doesn't freely rotate with my hand when cold...(or with the side of a screwdriver) In 40 years of using saws i've not seen this.. The 2nd time I used it I took the bar and chain completely off bc I thought the chain brake was stuck...If the chain was sagging to good when hot- and it tightens up so tight i cant hand spin it when cold- im gonna be forced to loosen it on startup-- then tighten it... just seems excessive compared to any saw ive owned... I can go out and hand spin any cold saw i have- new chain or not-- but not this saw?
How does the clutch/ sprocket turn if you have the bar an chain off? Next,where do you have the oil set at? I just checked mine and it turns freely. If nothing else I would take it back to the dealer being a new saw. Good luck.
oil is wide open.... ill check the sprocket when its cold--- (its 10 out so shouldnt take long)
Saw cooled down-- double checked chain-- have slack but wouldnt budge even with tool-- pulled bar and chain-- sprocket and clutch drum cant be spun by hand...they are tight as ****-- id pop the clip but bc this saw is new im heading to the dealer as something isnt adding up here...
Metal expands when it gets hot snd contracts when it cools.
A relatively tight chain when warm will turn into a really tight chain when cooled.
I always give the chain some slack after cutting if I am going to leave the bar and chain on.

Yep. That doesn't sound good. Let the dealer **** with it.
Guess I glossed over your post right before mine.
Did you check the brake? Pull back on the handle...
I might check if chain pitch matches bar and sprocket. Dealer could have assembled it with miss match.
