ttr 125 leaking gas when starting and smoking

I have a friend with a ttr125 that has a couple issues.

1. When starting ever time you kick it over gas comes out of the drain tube from the carb. Any idea what would cause this?

2. The bike is also smoking a blue smoke. I am assuming it is burning oil. I am seeing this could be a sign it needs a new top end. Any easy things to check first?

1.  your float level is to high

2.  check your oil level, make sure it is not overfilled.  after that run a compression test

Also your float valve might not be sealing properly, check its rubber and if there is any crap/scratches/chips/burrs on the sealing surface
