I wanted to get this flywheel off today and didn't have access to a removal tool this is the flywheel on a 028WB I don't know if the other Stihl models use this design or not I haven't checked yet, but here is an easy way to make a removal tool if you have access to a welder and saw, Take a piece of 1/2" pipe threaded and cut about 1/2 of the threads off of one end of it, now cut the pipe about 1 1/2" long, get a 1/2" bolt and nut (after building mine I would recommend using a fine threaded nut and bolt) and weld the nut to the end of the pipe making sure to leave space for a wrench to get on the nut, now thread the pipe into the flywheel insert the bolt and using 2 wrench's, one holding the nut and one on the bolt run the bolt in and the flywheel will come off, I know the flywheel is a metric thread but the pipe will thread in 2 turns and bottom out on the flywheel inside without crossthreading or binding in the threads they must be the same or so close that it cannot be noticed.
