How to Attach a Spindle on a Weedeater Engine

Many people have been asking me how I attached the spindle on my chainsaw powered bicycle. Well, I used pretty much the same method to attach it as I did on this weedeater engine. However, this is the simplest way to attach a spindle and probably not the best way, but it works. This method isn't always successful because the flywheel nut can come loose and send your spindle flying! And maybe even your flywheel, too!
