Common Issues With Briggs And Stratton Lawn Mowers
Briggs and Stratton lawn mowers can present several common issues. Understanding these problems helps you diagnose and fix them quickly.
Engine Won’t Start
An engine that won’t start often indicates fuel or ignition problems. Check the following:
- Fuel: Ensure you’ve got fresh fuel in the tank. Stale or contaminated fuel can hinder starting.
- Spark Plug: Inspect the spark plug for damage or carbon buildup. A worn or dirty spark plug affects ignition.
- Battery: If you’ve got a battery-powered mower, confirm the battery’s charge. Replace a dead battery.
- Starter: Listen for clicking sounds. If you hear clicks but the engine doesn’t turn over, your starter may be failing.
Poor Performance
Poor performance leads to uneven cutting or stalling. Consider these factors:
- Blades: Dull or damaged blades cause a poor cut. Sharpen or replace them as needed.
- Air Filter: Clogged air filters restrict airflow. Clean or replace the filter to improve performance.
- Throttle Settings: Ensure the throttle is set correctly. Improper settings can reduce engine power.
- Fuel Mixture: Check the fuel-air mixture. The wrong ratio can cause stalling or rough running.
Excessive Smoke
Excessive smoke can signal serious issues. Pay attention to the color of the smoke:
- Blue Smoke: This indicates burning oil. Check for oil leaks or overfilling your oil reservoir.
- Black Smoke: This often means too much fuel or a clogged air filter. Review the air filter and adjust the fuel settings.
- White Smoke: White smoke points to coolant entering the engine. This can indicate a blown gasket requiring immediate attention.
Addressing these common issues efficiently can restore your Briggs and Stratton lawn mower’s performance.
Tools Needed for Repairs
Gathering the right tools makes repairing your Briggs and Stratton lawn mower straightforward. Here’s what you need to get started.
Basic Hand Tools
- Wrenches: Use a combination of metric and standard-sized wrenches to tighten or loosen bolts.
- Screwdrivers: Both flathead and Phillips screwdrivers help in removing various covers and components.
- Pliers: Needle-nose pliers assist in grasping small objects or wires during repairs.
- Socket Set: A socket set allows for efficient removal and attachment of nuts and bolts.
- Torque Wrench: Using a torque wrench ensures proper tightness, preventing damage from over-torquing.
- Spark Plug: Replace a damaged spark plug to restore engine starting and performance.
- Air Filter: Install a new air filter to improve airflow and engine efficiency.
- Blades: Sharpen or replace dull blades for a clean cut and optimal lawn appearance.
- Fuel Filter: A new fuel filter prevents debris from clogging the fuel system.
- Battery: Swap out a dead battery to ensure reliable starting and operation.
Having these tools and replacement parts on hand simplifies the repair process, allowing you to quickly address any issues and get your lawn mower back in action.
