Go ahead, drink the Kool Aid.
My primary firewood saw has been my 028WB that I bought new in 1982. Love it!!
I rebuilt an MS261CMZ that had been run on lean gas/oil mix about 3 years ago and have been using it more and more. The first couple times I ran it, I pulled the muffler and checked the piston after each use, No problem. I use this saw more than my trustworthy old 028, which has cut 120+ cords of wood since new. I LOVE how the Mtronic saw starts and runs! After 3 years, I trust it and hope to keep it for the rest of my life. I still use the 028 at my lake house, but its has an easier life now, it lounges at Lake Anna and gets fed nothing but Moto Mix for its occasional workout.
CMZ (Mtronic saws) have virtually no problems that aren't mechanical in nature- bad gas, clogged fuel filter, gross operator stupidity, etc. Very rarely does a solenoid valve act up. or is there any electronic problem. I believe in Mtronic and look forward to the next generation of electronic engine management. Seriously, does anyone miss breaker points or Tyrannosaurus Rex?
I certainly don't.
Get an Mtronic saw and treat it with respect. Its a fantastic unit.
