Husqvarna 435 not running right

[Morganheightsdiscgolf@gma]

I've only cut about 9 times with this saw since I got it for my birthday last year, upto two days ago when. I replaced the chain it's been running very funny. It's been smoking more, it bogs down on any medium sized tree and now its having problems turning on. It also started shutting off when applying the chain break after a cut. Anyone have any ideas? This is my first chainsaw btw!

What fuel do you use? If you mix your own, how old is it?
Besides that, the first thing I would try is retuning the carburetor, there are good videos on youtube on how to do that, I recommend the one by steves small engine saloon.
Also, welcome to Treebuzz.

Recheck the chain pitch and gauge, pull the muffler off and have a look at the piston looking for scoring. Is the chain break still activated? Is you clutch cooked? Is the chain properly seated on the drive sprocket/rim?

Clean the air filter too
