I've read about all of these breaking and mine did today. what a surprise. I thought mine was new and improved but obviously not. All in all, not a bad repair bill for five years of tough duty. GEO
Mine fell off within 6 months. So I pulled a knob off an old stereo and put some superglue on the inside. 2 years later it is still attached.
We have about 5 stihl blowers and all of the knobs have come off time after time. Finally we got sick of it and bent the choke shaft slightly, now you can flick the choke on and off easily and no more losing knobs.
