OMG guys don't glue these.... Please.
If you run like we do ..Full Throttle they will fly off like a bullet from a gun....just Ebay replacement flywheel. ...
If you run "full throttle" they will never fly off......It's when you come to a stop that the problem shows up. Since the magnets will be attracted to the stator plate, it will pull and possibly overtake the 35-45 year old epoxy glue that they used to install them. Go to pull the cord and "clunk" and locks up as the magnet wedges into the stator......not that its ever happened to me
The lighted flywheels are most problematic since there is always pull on a magnet when at rest (plus they have a magnet and a metal shim glued to that).
Here's a visual aid.....pretend these little girls are magnets in the flywheel
for the OP, the magnets need to go in certain order. "south" needs to be the first to meet the stator as it spins around. You can use a compass to find S and N just bring the face side of the magnet up near the edge of one and it will draw to it. they also need to be right where they were on the flywheel in order to maintain proper timing. And if the flywheel was dropped, a real good inspection of it would be in order to make sure it didn't crack or go out of shape etc... Direct replacements are not available, ones off of donor flywheels are about your only option.
