Found the two problems. gas valve was not working right letting gas by. then the needle was not setting to keep it from going through carb and it to piston. just sitting there with that pressure was letting it pass by rings. it is all fixed now and running good.

I have a yahama big bear 300 and gas is mixing with the engine oil. What could be the causes of this? It does not smoke and it still runs good.
