Right, which is all fine and good.
When they run, they run smooth - I agree.
Until you get an issue with these saws.
How to diagnose it, you follow the correct steps to fix, and it still won't run correctly.
Is it the carburator? - You can't buy these non OEM - huge factor/huge price
Is it the solenoid - ok try it, it's not cheap or crazy expensive, but you have to replace it, it might be it.
Is it the wire or harness - Ok these are cheap - but rarely the issue.
Is it the ignition module? - if so, you are out of luck and have to pay 1/3 the price of a new saw (atleast here in EU) - try your luck......
If this doesn't work - you have to go back, did you overtightned the solonoid scews, or is it just the fact you can't reset the ignition module to factory settting or update it via Stihls mtronic program....the list of "maybe it's ..." goes on forever, which is NOT the case on a non Mtronic/Auto tune saw.
I loved my Stihl MS261 Mtronic, it ran so good, untill it didn't - and I was lucky to have Stihl repair it, free of charge (it was an early model 2014, fixed free of charge in 2022 by Stihl).
It came back to me with a 32 page book of diagnostic and repair/replacement on the ignition module and solenoid.
This is where I decided to sell it, and replace it with an MS261 non Mtronic.
I ain't about to give up my rights to selfrepair, not now, not ever.
No matter how nice "auto" carburator setting is.
