Thank you for the advice. Will ask my neighbor to help me on this tomorrow. I have one more Lawn Mower problem:
Few days ago, I have the lawn mower first run and it started easily, but the blade screw was a bit loose and sound odd. So I stopped it immediately. After tightened the screw, I cannot start it any more. I have changed a new spark plug today but have not test it according to your method yet. But now, once every 4 ~ 5 times I try to pull to start it, the pulling rope seems got stuck after I pulled approximate half of the rope length, in fact, it seems even pulling back away from me too. It really hurt my right arm now. Any one know what is the reason why? and how to fix it? Thank you.
