I tried to give you a reason in post #21. Are you here on behalf of management to make activity on this site?
How about you can push down harder on the ms261 or pull up harder if going up, or twist harder if using that technique.
I use 30cc saw and let the saw do its work. Not sure how much pushing would be effective on quite hard wood even with 50cc saw. Maybe some.
Can you reference the twist technique to some youtube video ?
Someone mentioned trolling. If you mean trolling for informarion, than you may be right, lol.
