Weed Eater Q4.75 Horsepower Briggs & Stratton Model # 961140004 02 Serial #030706M 010924 My lawn mower will start and run for about 10 seconds and then, it dies. It will start again and do the same thing. After about 3 or 4 tries, it will not start at all. It has a new sparkplug in it. The filter isn't too dirty and it is full of fresh, clean gas. I checked the oil and it is fine.
