LOL!!! OK now we are both morons...
Witness mark helps when making the rough adjustment, But it is stihl better for 87% of the population to have the screws on the right side...and you are the only one I know of that tunes a saw the way you do. No lesson needed from you on how to tune a two-stroke, as I have plenty of experience tuning two-strokes that cost in excess of $15,000. The real way to do it is by holding the saw at WOT and leaning the mixture to the two-four break, then back a slight amount. Do a search on this site and you will see the light.
The offset is in the Elastostart handle to even the force in the fingers. My E-start handles never move...you must not have enough preload in your rewind spring...limp as it were...BTW, please provide figures on the weight difference between the standard handle and the Elastostart handle since you claim it is a significant difference.
Are you up to 3 million trees yet?
I can assure you I understand physics...even have a college transcript to prove it. Your handle argument is flawed. A handle that is meant to be held in only one way might be oval or approach square (think Colt 1911 grip), but a handle that must be held in many positions must be more rounded, as the Stihl rear handle is shaped. No one needs more leverage on a handle than a weightlifter, hundreds of pounds in each hand. The grip area on a weight bar is round.
You started this thing digging yourself into a hole with a shovel...but now you are using a backhoe and it is getting bad. Good luck!!!
Happy sawing!!!
