I found this site while I was googling images,for a Briggs and Stratton "NPR" like mine. A pic came up of a similar "N" on this site. When I saw this was a motorized bike site I just had to join,because I happen to have an old Whizzer also. I have 3 incomplete engines and lots of other parts for it,but not enough to get it together yet. I love restoring things,especially when it is motorized.I'm a mechanic by trade so I'm always wrenchin on something anyway.
