Will not run under load, seems to be starving for fuel. When I leave it for a minute or two, I can start it and work with it for a minute or so then it sees to over rev before cutting out. If I start it immediately it will run for a few seconds and cut out again.

Check the fuel filter in the tank for plugging. Check the fuel lines for kinks, rotting, or splits. Check the muffler and air cleaner for plugging. Make sure all the screws and mounting nuts are tight on the carburetor. When these things look ok, then turn the H needle jet CCW about 1/2 turn, start the engine and let it warm up. Open the throttle fully--the engine should be 4-stroking now. Proper adjustment is when the engine will 4-stroke, but immediately 2-stroke when cutting. You may need to turn the H needle somewhat CW to achieve that condition. Hope this helps!

I had the same problem and the same solution. I suspected gas issue because the engine would run fine for 2-3 minutes and then cut out. As a solution I removed the gas filter and surprise, the saw worked like new. I am off to the store to buy a new filter.....
