On mine, the screw was bigger than the hole at the end, so there was no way to get it out. I used a hacksaw and sawed lenthwise down the shaft (the clutch housing) on the edge so I could see where the drive shaft was (you don't want to cut this). Then I cut accross the shaft (clutch housing) to expose the inside. Now I use a common screw driver and take the screw out. It also take a tourqe (star) wrench like the other screws. I guess if I don't replace the clutch I'll use it for a RC boat or something...

You need a long skinny T25 torque driver (sold in a pack at Lowe's with 3 other sizes.)
Take off the 4 screws in the back to reveal the piston. Get a wooden dowel (or a wooden spoon if your wife isn't around) and stick it in to the piston to block it from spinning.
Now take that T25 and stick it in to the front pulley (cone shaped silver item that is preventing the housing from coming off) turn to the left and it should come off.
That should come off to reveal about a 1"x1.5" piece with a spring wrapped around it. That can also turn to the left and come off with an adjustable wrench or pliers.
Once that is off the housing should come away and you'll be able to get at the pull cord after removing 4 more T25 screws.

The starter assembly is between the motor and boom so you have to remove the boom from the motor housing. Usually one nut & bolt at the nose of the starter housing. There may be another lock bolt. You shouldn't have to remove the throttle cable and leads but it depends on how tight the factory installed them. Remove the starter housing. If you're real lucky all you have to do is pull some starter rope up past the pulley and wind the pulley in the direction the rope pulls back into the housing. You have to pull the rope around the pulley as you wind it. If the spring catches and builds tension you're good, wind it four or five times or enough to fully pull the rope back in. If the spring doesn't catch or releases every two or three turns it has to be replaced. You may have to replace the spring and container (PN638033001) and/or the easy start assembly (PN310022001).

Check your lube oil. If the engine got stored upside down for a while since you last used it, lube oil has drained out of the reservoir, and the engine won't allow you to pull the cord to start it with no oil in the reservoir.
If that's the case, you've got lube oil in the cylinder. You will need to remove and clean the spark plug, and drain the oil out of the cylinder through the spark plug hole. Reinstall the spark plug, then refill the lube oil reservoir per the user manual.
