The bolt holding in the clutch cover is a torq not a allen wrench, also, when you get the cover off, you have to hold the motor in place with something (I used a Screwdriver) then in the direction of the "off" arrow, you have to use a punch or screwdriver/hammer combination to get the clutch off before you can get to the pull-cord assembly. You do not need to remove the springs from the clutch. It should be easy from there.
