Weed Eater FB25 No Spark

I have a Weed Eater FB25 that I can't get to start.  It has no spark on the spark plug.  I've changed the plug and the ignition coil.  Is there anything else I can try?  HELP!!!

    Disconnect the "kill switch wire" from the coil and re-check.
     
    Also, with the flywheel clean of rust re-set the "air gap" (space between coil and magnets) using a business card.
     
    If you still have no spark, the coils bad... Just because it's new doesn't mean it's good..

    I figured out it was the flywheel.  The key was broken off.  I was able to get a used one and changed it.  It did start and run for about 10 seconds and then the second flywheel's key broke off.  Is there any reason that 2 flywheels broke?  I've ordered a third one and I really don't want this to happen again.  Anybody have any ideas?????

    Sounds like the flywheel nut wasn't tight enough OR the air gap, space between the coil and flywheel is too tight causing them to rub...
