Hello gang , I have an Craftsman 550 Series Briggs & Stratton Engine Model No. 944.361300 . My blade hit a metal post couple of times , and the last time the engline start to be less strong , like if the motor does't run as fast. Check these videos please. Can this trouble and weak power can be cause by the shaft ?
