Ahhhhhh, The full throttle debate. First, let me paint a picture; something like this. Off in the distance, you hear that high pitched wheeze, zing whatever, cutting through the air. A poor little 2 cycle engine screaming at the top of its lungs (if it could be translated into English, it would be screaming, God, take my life now). Then you notice the lawn technician with that white knuckle, death grip on the throttle, trying to get 4 million rpm's out of that poor little 4 stroke. What's he doing? He's curding a piece of grass with a plastic string. Let me cover this again for the S L O W readers. We're using a plastic string, spinning at several thousand rpm's C U T T I N G A B L A D E O F G R A S S ! !
This is a personal pet peeve of mine; can you tell? Anyone that ever has, ever does, or will ever work with or work for me, knows they won't have a job long under this scenario ;o)
Under normal working conditions, (excluding the rare occasion of cutting really tall grass, on a bank, etc...) a string trimmer shouldn't be working anymore than 1/3-1/2 throttle. Heck, half the time, on a weekly cut, I walk around with my string trimmer at idle; it cuts perfectly.
