Gasoline in the carburetor of your lawn mower does not take kindly to time and the lower temperatures of winter. The gasoline gums up, leaving deposits that can clog the tiny ports of your carburetor. When you try to restart it after the winter, there’s no gasoline flow to your engine and it does not start. Other issues are condensation in the crankcase, dirt and accumulated gunk in the undercarriage, and the potential for rust in the controls and linkage. Do your mower a favor. Before you put it away for the winter, follow these steps. Of course, if you can’t find the time or don’t feel confident, Mr. Mobile Mower is always there to help. See our “Services” section for our winterizing package.
1. Remove the gasoline in the tank. This can be done by siphoning the contents in the tank into a plastic can or pulling the fuel tube from the carburetor.
2. Run the engine until the remaining fuel is completely consumed and engine stops.
3.Remove the spark plug, put lubricating oil (about 50 milliliter) through the opening, and crank up the engine using the rope, so the piston and crankshaft are lubricated.
4. Clean the undersides of the lawn mower to remove traces of grass and muck attached to the blades and clean the working parts of lawn mower. Remove any foreign material lodged between blade and body. Check the blade for cracks, large nicks and general condition. Remove it if it is damaged so that you won’t forget in the Spring. NOTE: Always disconnect the rubber spark plug wire from the spark plug before working under a mower. Today’s easy-start mowers can start with just a small movement of the blade!
5. Replace the spark plug!
6. Lubricate linkage and control surfaces.
7. Generally clean the mower, paying special attention to the cooling fins and throttle plate areas.
