I was just reading the posts on the m200 chainsaw and found it interesting to see all these adjustments that are being made on saws. We bought this pole saw this spring, for pruning 20 to 25 year old cherry trees. I usually use our man lift for this job. It was a lot harder workout with the pole saw. Time wise was about 1/2 less. I also spent about a week modifying the damn thing, removing spark arrester, leaning it out. It was running really rough until we started running high octane fuel in it. Our rep said that all Stihl saws should be run with high octane fuels, I've since switched all our saws over and I hate to admitt it but the rep was right.
