Mowing the lawn shouldn’t be a chore. It should be a relaxing experience, allowing you to enjoy the fresh air and the satisfying feeling of a perfectly trimmed lawn. But what happens when your Honda lawn mower suddenly becomes a sluggish, slow-moving beast? Frustrating, right? Don’t worry, the culprit could be a simple adjustment to the speed control. In this comprehensive guide, we’ll explore the common causes of speed problems in Honda lawn mowers and delve into the steps you can take to adjust the speed control and reclaim your mower’s power. We’ll also provide valuable troubleshooting tips and safety precautions to ensure a smooth and efficient process.
Overview
The speed control on your Honda lawn mower is responsible for regulating the engine’s speed, which in turn determines the mower’s ground speed. If your mower is moving too slow, it could be due to a number of factors such as a clogged air filter, a dirty carburetor, a faulty governor, or simply a misadjusted speed control cable. By understanding the different components and adjustments involved, you can quickly and effectively diagnose and resolve speed issues, ensuring a smooth and efficient mowing experience.
Identifying the Speed Control Cable
Before diving into adjustments, it’s crucial to locate the speed control cable. This cable connects the speed control lever on the handle to the engine’s carburetor. The cable’s length and tension determine how much fuel is supplied to the engine, impacting its speed.
Finding the Speed Control Cable
- Locate the speed control lever: The speed control lever is typically located on the handle of your mower, usually near the engine’s throttle control.
- Trace the cable: Look for a wire-like cable running from the speed control lever. It’s often encased in a protective sheath.
- Follow the cable: Follow the cable as it runs towards the engine. The cable will connect to the carburetor, typically near the throttle linkage.
Adjusting the Speed Control Cable
Once you’ve located the speed control cable, you can begin the adjustment process. The adjustments should be made with the engine off, and the spark plug wire disconnected. This will ensure your safety and prevent accidental starting.
Step-by-Step Adjustment Instructions:
- Loosen the cable lock nut: Locate the lock nut that secures the speed control cable to the carburetor. Use a wrench to loosen it.
- Adjust the cable tension: You’ll likely find an adjustment nut on the cable itself. This nut controls the tension of the cable. Turn the adjustment nut clockwise to increase tension and counter-clockwise to decrease tension.
- Test the speed control: Start the mower and observe the speed control lever’s operation. Adjust the cable tension accordingly until the desired speed is achieved.
- Tighten the lock nut: Once you’ve achieved the desired speed, tighten the lock nut to secure the cable in place.
- Test the mower: Run the mower for a few minutes, ensuring smooth operation and consistent speed across all speed settings.
Troubleshooting Speed Control Issues
If adjusting the speed control cable doesn’t resolve the issue, there could be other underlying problems.
Common Issues and Troubleshooting Tips:
1. Clogged Air Filter:
- Symptom: Reduced engine power and slow speed, even with a fully adjusted speed control cable.
- Troubleshooting: Remove the air filter and inspect for dirt, dust, and debris. If necessary, clean or replace the filter.
2. Dirty Carburetor:
- Symptom: Engine sputters, stalls, or runs unevenly, impacting speed.
- Troubleshooting: Consult your Honda owner’s manual for instructions on cleaning the carburetor. This may require specialized tools and knowledge, so consider seeking professional assistance if necessary.
3. Faulty Governor:
- Symptom: Engine doesn’t respond to throttle adjustments, resulting in inconsistent speed.
- Troubleshooting: The governor is a complex component and requires expertise to diagnose and repair. Contact an authorized Honda dealer or a qualified mechanic for assistance.
4. Damaged Speed Control Cable:
- Symptom: Speed control lever doesn’t respond smoothly, or the cable feels loose or frayed.
- Troubleshooting: Inspect the cable for damage and replace it if necessary.
Maintaining Proper Speed Control
Regular maintenance is key to keeping your Honda lawn mower running at optimal speed.
Maintenance Tips:
- Clean the air filter regularly: Remove dirt and debris that can obstruct airflow and affect engine performance.
- Inspect the speed control cable: Look for signs of wear or damage and replace it if needed.
- Use high-quality fuel: Always use fresh, clean gasoline as recommended by the manufacturer.
- Perform regular engine maintenance: Refer to your owner’s manual for recommended service intervals.
Safety Precautions
When working with your Honda lawn mower, always prioritize safety.
Safety Tips:
- Disconnect the spark plug wire: Always disconnect the spark plug wire before working on any engine components.
- Wear appropriate safety gear: Use eye protection, gloves, and sturdy footwear.
- Read and follow your owner’s manual: Refer to the manual for specific instructions and safety warnings.
- Seek professional help when needed: If you’re not comfortable performing certain repairs, consult an authorized Honda dealer or a qualified mechanic.

FAQs
Q1: What is the speed control lever on a Honda lawnmower?
The speed control lever is a crucial component of your Honda lawnmower, responsible for adjusting the engine’s speed and ultimately determining how fast your mower cuts the grass. It’s typically a small lever located near the handlebars, allowing you to control the engine’s RPMs. The position of the lever determines how much fuel is supplied to the engine, impacting its power and speed.
Understanding and knowing how to properly adjust the speed control lever is crucial for optimal lawnmower performance, allowing you to tailor the cutting speed to different grass conditions and personal preferences.
Q2: Why might I need to adjust the speed control lever?
There are a few reasons you might need to adjust the speed control lever on your Honda lawnmower. One common reason is if your mower isn’t running at the desired speed, cutting the grass too slow or too fast. Another reason could be that the engine is struggling to maintain a consistent speed while mowing, especially on hills or in thick grass.
Adjusting the speed control lever can help address these issues, ensuring your mower operates efficiently and smoothly.
Q3: Where is the speed control lever located?
The location of the speed control lever can vary slightly depending on the specific model of Honda lawnmower you own. However, it’s typically found near the handlebars, on the right side of the mower. Look for a small lever with markings or indicators for different speed settings.
Some models may have the speed control lever directly on the engine itself, requiring you to reach down to adjust it. Refer to your owner’s manual for the exact location on your specific model.
Q4: How do I adjust the speed control lever?
Adjusting the speed control lever is a simple process. First, locate the lever near the handlebars or on the engine, depending on your model. Once found, move the lever to the desired speed setting. If the engine is running too slow, move the lever towards the “fast” or “high” setting. If it’s running too fast, move it towards the “slow” or “low” setting.
Remember to listen to your engine and observe the cutting speed. You should be able to adjust the speed control lever to achieve a comfortable and efficient cutting speed.
Q5: What if I can’t find the speed control lever?
If you can’t find the speed control lever, it’s possible your model doesn’t have a traditional lever for adjusting engine speed. Some Honda lawnmowers use a different system, such as a throttle cable connected to the engine. In this case, you may need to adjust the cable tension to change the engine speed.
Refer to your owner’s manual for detailed instructions specific to your model. If you’re unsure, it’s best to contact a Honda dealer or certified mechanic for assistance.
Q6: What are the signs of a faulty speed control lever?
A faulty speed control lever can manifest in various ways, impacting the performance and reliability of your lawnmower. Some common signs include the engine struggling to maintain a consistent speed, the lever feeling loose or unresponsive, or the mower not reaching the desired cutting speed.
If you experience any of these issues, it’s important to have the speed control lever inspected and potentially replaced by a qualified technician to ensure safe and efficient operation.
