I read this as a 2 year old comment under a 2016 youtube video about the Stihl ms261 C-M:
"The problems with the M-Tronic system isnt the system itself. Its the solenoids on the carbs. They have plastic internals that are delicate to ANY kind of grit that can pass through the 30 micron fuel filter. Stihl knows this. I'm a Stihl technician. They are working on solenoids that have metal internals that still are as flexible as the plastic ones that can withstand any grit. They cant use a more restrictive filter because it restricts the fuel flow too much. 99% of the M-Tronic problems will be solved by a new solenoid and resetting the controller back to factory settings. Just keep your fuel, fuel cans, and around the fuel cap clean and itll help alleviate the problem."
Does anyone have any idea if Stihl is currently using other solenoids on the carbs and if the M-Tronic system should no longer be feared?
