I asked the small engine guy I took my Ariens snowblower and cub cadet lawn tractor to about this and he hadn't heard of any issues so far. He gets all his Stihl parts from a small local shop.I rarely repair them for customers also now. The dealers near me will still sell parts, but with the parts prices being what they are I have to believe they are incentivized to push customers into new equipment. Last time I was quoted a price for an ignition coil for a fairly new saw it was half the price of a brand new saw.
