The idea of not mixing gas is appealing
And not rebuilding carbs when they get gumed up
I will say I am amazed the last three years using the Stihl Motomix in my saw and weed eater that even without running them dry I have had zero carb issues and they run a lot cleaner and start first pull even if it has been several months since I used them. That being said, the idea of a battery powered limb saw is attractive.
