As I was mowing, I realized once the lawn mower started spitting up oil and smoking that I didn't tighten the oil cap and it came loose. I washed the lawn mower once it cooled down and I cleaned it up but every time I use it, after about 10 minutes it starts to smoke and get hot again and it starts to smell so I stop using it. I'm scared it will overhead blow up on me:) Should I be okay to keep using it and this problem with go away or did I wreck something and need to get it looked at?
