    Crater...The emmision police gave Kohler a huge headache a few years ago when the told them that the adhesive they used was not compliant ...
    They had to use a lesser glue on their magnets...
    Use JB Quik Weld...sets up in about 5 minutes in 80 degree temps..
    Use 1 inch strips of thick cardboard and bend them in half...in a vee..
    Insert them between the magnets while gluing...watch your spacing..
    I usually mark the previous locations on the flat area on the flywheel..
    Make sure the magnets and flywheel are CLEAN...
    You can keep slightly repositioning the magnets until the JB Quik starts to set up...
    CAUTION...if the flywheel magnets migrate to each other..the flywheel will be out of balance...and COULD take out the machined bushing in the top
    of the block...which is not replaceable...
    Just keep an eye on it till it dries....you'll be ok...

    I know it's late and hopefully you got it fixed but I had the exact same problem. I tried everything it took me almost My problem ended up being a collapsed lifter. I had the exact same problems to a T. Hope this helps

    Ground check a must, powder coating bad news. make sure ground bolt is not black but silver, not been pressure washed, shake ecu harness while running at ecu see if clears, also check fuel pressure at rail at valve cheap tool at auto parts store. Also check power and ground connections on coil make sure tight and not dirty. Also what year is unit?
