Motorcycle Repair: 2002 honda crf50 not starting, oil mixture, gas tank

Question
Hi
My son received a secondhand crf50 yesterday and rode it for an hour.  It was going perfectly.  No problems.   Started it up for 10 mins before school this morning.  No probs.   Came home from school to take it riding and it simply wouldnt start.  Any suggestions would be appreciated.

Answer
