I am geting gas and oil mix in the air box filling it up! Any help on way!

 

Does it run? Sounds like a bad case of blow by

 

Thats my thought also. Maybe the rings have seen better days.

 

Yank off the plug wire, pull off the oil fill cap and spin it over and see if you have pressure come out.

 

Sounds like carb has leaked fuel into engine oil an when you crank atv up there to much fluids in engine so the crankshaft is turning an pushing the mixure out any were its cann.Check the oil level to see if its over full this would be an good sign that this is what happened..Sometime carb float value;float needle] will bypass when atv is hauled with fuel value turn..when atv bounces on trailor the float is doing the same thing bouncing with this needle attached it an this sometimes causes the bypass..if atv hasnt been transported then sometime the spring loaded needle in float value cannot keep tension on seat an this can cause the bypass or water or dirty needle seat can also cause an bypass so IMO i would check oil level first then we all can go from there.
