Motorized Bicycle Centrifugal Clutch Install

I have been building motorized bicycles for about 1 1/2 years now, and made about 15 of them so far.  Mostly beach cruisers with a few mountain bikes, and more recently a chopper and my most current and favorite...a chopper spoiler.  Finally a chance to post an intructable about how to install a centrifugal clutch.  There is one site available online that has something similar (zoombicycles.com), and I will use some of there help and maybe even pics, but I will incorporate more pics of my own and further detail for everyone's questions about a cent. clutch and/or pull start

Tools You Will Need:
Flat-head Screwdriver
Phillips Screwdriver
Allen wrench (To lock gears from turning)
Ratchet with 13mm Socket
Threadlocker
Gear/Clutch Puller
