For anyone like me who is embracing the old technology of 2002, I found two very useful game sources that open in Flash MX,:
A walking Mario character: http://www.flashkit.com/movies/Games/Full_Game_Source/Walking_-Matthew_-7690/index.php
A Platform game with levels( not side scrolling, but good enough)
http://www.flashkit.com/movies/Games/Full_Game_Source/Xtreme_P-Matthew_-7635/index.php
If anyone knows a side scrolling one too that would be good.
