Ms 261 won’t idle

[Skeena2]

I’m having trouble with my ms261. It is hard to start. When I get it running it won’t idle. The saw is 5-7 years old. It’s the Mtronic version with the captured bar nuts. So I started by replacing the fuel filter. Then the spark plug. I cleaned the air filter and put new gas in it. I removed the spark arrestor. None of the parts replaced or inspected looked faulty. The problem still persist. I have already used it to cut a trailer load of firewood this year prior to these issues. What should I try next?

Try a new fuel solenoid.

Try a new fuel solenoid.

AND the replacement fuel pickup/filter. Both should be in an upgrade kit.

Have you done a reboot yet?
