The worst models for the magnets coming loose were the two stroke Huskys, the two strokes resonate at a higher frequency and the resonating vibration loosens the magnets but the problem is still there never the less on the four stroke but not as bad. And another reason for this could be the thickness or lack of it of the aluminum hub of the flywheel, with it being aluminum it is much more susceptible to distortion and expansion.
The Husky 610 suffered the same problem but this was due to the compound used to adhere them in. I have re-bonded SEM magnets with the same compound as I use to rebond the magnets in the 610 with no reoccurring problem, but with the SEM you have to catch the loose magnets before they break up.
