Chain saw question

[Henro]

I have a Stihl arborist saw M 192TC model. It starts and seems to run fine except for one thing.

If I pull the trigger all the way it wants to cut out. I mean, it loses power and the speed drops. If I hold the trigger at 90% or maybe 95% it runs at full speed and sounds totally normal.

I’m not sure what the message is here. Is this a common symptom of something?

I will check my air filter after posting this. Something I should’ve done first thing I think. Just getting this saw ready for first use after sitting during the winter, spring and at this rate most of the summer. The small Dewalt 20 volt battery chainsaw is too convenient for small jobs around the place.

First things I would check are:
Air filter, fuel filter, spark arrestor.

Well, I’m embarrassed to say it. I cleaned the air filter and that solved the issue. Something I should’ve done before posting I realized as I was posting that, but since I typed it, I figured I better get some extra ideas just in case.

I guess my past experience must be nothing comes easy! But this time it did!

Thanks for your advice Evil Twin!
