husky problem

Need a bit of direction with a saw. I have an older Husquavarna 266 that is gutless. Idles fine, revs up under no load, air cleaner clean and the compression feels good when it's being pulled over. I have adjusted the high speed jet in the cut and I can't keep the revs up under load. Bogs out every time and I have to let up or stall it. Would appreciate suggestions on what to try.

Fuel filter clogged up?

Lets though enough fuel to start and idle, but once you load the engine up it starves?

It actually revs up and sounds normal so I had not thought of the filter. I will look. Thanks

Air filter thought: Nylon filters can appear clean with no visable sawdust. But they can still have a thin film blocking the mesh.

Probably the spark arrestor screen in the muffler.

All good suggestions.

Something is clogged up. Fuel, air or exhaust...

Thanks for the responses, took the saw to the firewood pile today along with a loner to actually cut and after cutting for a bit decided to trouble shoot the 266 in the cut. Took off the breather cover thinking I was going to remove the filter to test the saw and immediately saw the problem. I had had the cover off and checked the filter but in poor light so I didn't notice a solid thin covering of what looked like soot on the filter media. Scraped it off and then the saw wouldn't run at high speed, I had choked the high speed jet down to get it to rev with the available air. Readjusted the jet and the saw cuts well again. Feel a bit silly but I am used to the old style filters. Live and learn. What is the suggested method for cleaning these filters on the fly? Thanks again for the suggestions.
