Two cheapo ft magnets were too weak for mine in 650 with a full tank, I just stuck three in the switch and my nems great now. They do break easy though so I'm considering getting some stronger magnets to replace them soon (stronger so they don't break, and stronger magnetism so I can use two of em). I have a habit of dropping things so it's only a matter of time...
Tried it but still get crunch even with magnets but no where near as bad with spring
Flat top and got magnets in and usesd a dremel but don't wanna go to far and mess it up lol
