My Electric Start Quit Working ! What's Wrong?
The most common problem with an electric starter that won't work is not an electrical one but is usually a problem with the plastic starter gear on the engine. The starter motor is on the back of the Briggs & Stratton engine near the left side of the lawnmower's bumper. It is slightly larger than a Coke can and the top of it is covered with a cover held on with two small screws. If you are sure you have a good battery and a good electrical connection and you suspect a problem with the starter motor.... take the cover off so you can look at the top of the starter. It has a nylon "barber pole" that the gear runs up and down. When you turn the key it is supposed to fly up the pole and mesh with the gear on your flywheel to spin the engine until it starts. Does your gear still have teeth on it? If not... you need a new gear. They are cheap and there is a right and wrong way to put them one so ask your service center which way is "up". If you install a new one upside down it will break in half. Is the gear just stuck? Clean out the dirt and lubricate it and the pole a little. Is the pole wobbly? Buy a new pole with a new gear in a little kit for about $20.00. None of the above........... take it to a service center and get it tested. A new one is around $110. but nobody wants you to have to buy one unless you really need it.
