What's the issue?
i picked up this ms460 cheap ($400). when i got the saw it ran, but was very slow to rev, and would die after dropping down to idle. I took it to a shop(shop has 150 5star reviews out of 157 total reviews, literally the only bad reviews were for stuff like longer than expected turn around time, or price). I took the saw in without a bar and chain(didnt have one when i bought it), and the guy at the shop said it was time for a carb rebuild. I have him rebuild the carb, and a few days later I pick it up. when I picked up the saw i tested it(without a bar/chain obviously) it ran great. so I leave the shop and go get a bar/chain for it. after installing the bar/chain the video shows how it was running. so I text the guy and send him this video. he says he didn't adjust the carb because it ran good after the rebuild, and didn't seem to need adjusted. he tells me to bring the saw back in and he will adjust it. now when I get to the shop he says that he will have to order parts because the high idle screw is broken off. it has now been a week, and dude still hasn't finished the saw. granted he is an echo dealer, but all the stihl dealers/shops have "sketchy" reviews. should I just go get the saw and take it to a stihl shop, or hope dude gets his crap together and gets it done correctly?
