The first thing I would do is to check all the hoses off the carb on the outside of the tank(that area of those saws is prone to excessive heat which was one of the main cause of issues with them), treat it just like any other saw as far as checking the simple things first.
That's an older version of that saw, it's probably a 2012-2013, the primer bulb is dark and not clear telling me that the fuel system has some build up in it.
Check the fuel filter after looking the lines over, these are all the things you would check on any saw that had a fuel problem.
Check compression right away also if you can as that will give the same symptom you just described, if you can't check compression(it's a small hole) then pull the muffler cover to inspect the piston for scoring.
Don't keep running it until you find a problem and fix it.
