Ok so the other night while riding my four wheeler quit on me. Checked the oil. pretty dry I know thats never a good thing. so I tried to crank it back several times since then. Turns over fine doesn't hesitate so I know its not locked up but it still won't start. I am getting gas to the carb and it is firing. Thinking its something serious since oil is pretty crucial for a healthy motor. Anyone know what exactly it could be??
