I recently started to clean up my 10700 squarefeet property. I bought an additional 2 stroke weed eater, house brand from a local hardware store. Manual calls for 1:40, I ran the first tank 1:25 but I got some popping noise under load. I believe that is called "popcorning".
I do have 2 Stihl chainsaws, a MS170 and a MS180, both call for 1:50. I have a small bottle Stihl HP Ultra oil as well as a 5 liter jug of Stihl Motomix. (Alcylate fuel with 1:50 Stihl HP Ultra).
Now the question is: Do I run my chainsaws 1:50? On arboristsite.com I read that many professionals run 1:40 and get much more life out of their equipment, some even 1:32 or 1:25
First tank on my MS180 I ran 1:40, the MS170 still sits in the box. A disadvantage of the MS170 and MS180 is a fixed jet carb, only idle speed is adjustable.
So what do I do? Simply run Stihl Motomix straight? Mix additional Stihl HP Ultra an bring the mix to 1:45 or 1:40? Or do I create a leaned out environment and do more harm than good long term?
The weed eater will get regular gas with part synth. 1:40, done. Was cheap and if it breaks it breaks. I suspect the engine will be the last thing to go bad on that thing.
Thanks for your patience, these 2 Stihls and store brand weed eater are my first 2 stroke machines that I ever had.
