Stihl low on power

[TNhobbyfarmer]

My 025 Stihl chainsaw seems to be low on power. I am having problems cutting logs that it used to zip through. I put a new chain on and it's still not cutting well so it's not just a dull chain. Even though it starts easily and sounds like it always has, the engine appears to be running hot. There is smoke coming from under the chain cowling. I am thinking about one of two options. Either take it too a service center and have it serviced or just get a new one. I am worried about a large repair bill and not being satisfied with the results and then going on and getting a new one anyway. What would you do?

is the oiler working properly?

Was it going fine when you first started to use it that day but just seemed to de-power after a little while?

The muffler is probably fouled with oil.

How fresh is the gas ?

The muffler is probably fouled with oil.

Yep, soak in in gas overnight.

Replace the fuel filter, air filter and the spark plug. Also as suggested check the muffler, you could also take the muffler off and check to see if the Pistons scored. But definitely put new fuel in it as you might have a bad batch. (Make another batch)

Chain brake hanging up?

Chain oiler is my guess. Bar gets hot and expands causing chain to become so tight that engine can't turn it.

Make sure you have 2 stroke oil in gas.
