If you already checked the spark arrestor screen and it is clean and clear I would put a new OEM carb on it. I have replaced more of those single adjuster carbs on the 170/180 than on anything else. They are cheap at your dealer, around $35.00.

Just some of my thoughts
Maybe an old Stiff carb diaphragm ? Not flexing enough to open the meetering leaver. ?

Or just a dirty carb jet ?

So the $15 dollar one on Amazon is a no no?

The aftermarket carburetors are a crap shoot at best. As Brad indicated, new OEM for those saws is relatively cheap.

I ended up getting one of those carburetors with tune up kit from Amazon for $15!! Installed it and it runs perfect!!
