So I took my Puch out for a spin today. Omigod, cleaning up that carbon made it SO much faster. Before it was a strugle to get up hills, but now I fly up them at like 20-25mph. Thanks for all your help guys.
p.s. Pictures of my puch can be seen at: http://members.aol.com/txcpoison/moped
(the color is a bit off though)
