In the hot Perth climate, lawn mowers can easily overheat and start to smoke. To fix a smoking lawn mower, it’s vital to check the engine oil levels. You should also ensure the cooling system is working properly. Regular maintenance, such as changing the oil and cleaning the mower, can help prevent these issues.
Reading this blog post will guide readers through the steps to troubleshoot a smoking lawn mower. Understanding how to maintain the engine and cooling components can save time and improve the mower’s performance. With the right care, the lawn mower can stay in good shape even during Perth’s hottest months.
Identifying the Cause of the Smoke
To fix a smoking lawn mower, it is essential to find out why it is smoking. Several factors can contribute to this issue, including engine oil levels, air filter condition, cooling system performance, and potential overheating problems.
Assessing Engine Oil Levels and Quality
Checking the engine oil is a crucial first step. Low oil levels can cause the engine to run hot and produce smoke. To check the oil, remove the dipstick, wipe it clean, then reinsert it to see the level. If the oil is low, top it up with the recommended oil type.
Quality is also important. If the oil looks dirty or has a burnt smell, it may be time for an oil change. Old or dirty oil can cause poor lubrication, leading to engine wear and smoke. Changing the oil regularly helps maintain a healthy engine.
Checking the Air Filter Condition
The air filter plays an important role in the mower’s performance. A clogged air filter can restrict airflow to the engine, causing it to run rich (too much fuel), leading to smoke. To check the filter, remove it and inspect its condition.
If it appears dirty and clogged, cleaning or replacing it is necessary. A clean air filter ensures the engine gets the right mixture of air and fuel, helping to prevent smoking issues. Regular maintenance of the air filter enhances the mower’s efficiency and lifespan.
Evaluating the Cooling System
An effective cooling system is vital to prevent engine overheating. It helps regulate the engine’s temperature by dissipating heat. If the cooling system is not functioning well, the engine may get too hot and produce smoke.
Inspect the radiator and any cooling fins for dirt, debris, or blockages. Clean them carefully to ensure proper airflow. Also, check for leaks in cooling hoses. Ensuring the cooling system works well helps maintain the engine’s temperature within a safe range.
Inspecting for Overheating Problems
Overheating leads to smoke and potential engine damage. Besides checking the cooling system, it’s necessary to evaluate other factors that can contribute to overheating. This includes making sure the mower is not running for too long without breaks, which can cause excessive heat buildup.
Look for signs of overheating, such as a burning smell or hot engine components. If the engine is getting hot too quickly, there may be issues with the fuel mixture or internal components. Regular monitoring can help identify overheating problems early, allowing for timely repairs.

Routine Maintenance for Lawn Mowers
Routine maintenance is crucial for keeping lawn mowers running smoothly, especially in Perth’s heat. Regular checks and changes can prevent issues like smoking engines, and ensure optimal performance.
Conducting Regular Oil Changes
Regular oil changes are important for maintaining a lawn mower’s engine health. Fresh engine oil helps lubricate moving parts, reducing wear and tear.
He should check the oil level before each use and change it every 50 hours or at least once a season.
- Use the Right Oil: Refer to the manufacturer’s guidelines for the correct oil type.
- Draining Oil: Ensure the engine is cool. Use a suitable container to collect the old oil while draining.
- Refill: After draining, refill with new oil to the recommended level.
This can help prevent overheating and smoking.
Cleaning or Replacing Air Filters
Air filters keep dirt and debris from entering the engine. A clean air filter improves air flow, enhancing engine performance.
It is advisable to check the filter every month, especially during heavy use.
- Cleaning: If the filter is reusable, tap it to remove dirt. Wash it with soap and water, then let it dry completely.
- Replacement: If it’s damaged or too dirty, replacing it is the best option.
Keeping the air filter clean can significantly increase efficiency and prevent smoke from the engine.
Adjusting the Throttle Cable
The throttle cable controls the engine speed. An improperly adjusted cable can lead to poor performance and may cause excessive smoke.
She should routinely inspect the throttle cable for wear. Adjustments can be made as follows:
- Check Tension: There should be some slack in the cable. Too tight can restrict performance.
- Loosening: If necessary, loosen the cable adjustment nut and pull the cable slightly to create slack.
- Tightening: Ensure it reconnects properly without too much slack, then retighten the nut.
Proper cable adjustment supports smooth operation and reduces engine strain.
Utilising Injector Cleaners
Injector cleaners can help keep the fuel system working efficiently. Using these cleaners regularly can prevent build-up that might cause smoking.
He should look for products specifically designed for small engines. Follow the instructions on the cleaner for best results.
- How to Use: Add the cleaner to the fuel tank during a fill-up.
- Frequency: It’s effective to use injector cleaners every few months or after extended use.
This routine will help maintain the fuel injectors, improving combustion and reducing smoke emissions from the engine.

Advanced Cooling and Power Management
Managing heat and power in lawn mowers is crucial, especially in Perth’s hot climate. Key strategies include upgrading cooling systems, monitoring temperatures, and optimising power output. These methods help prevent overheating and maintain optimal performance.
Upgrading the Cooling System for Perth’s Climate
Improving a lawn mower’s cooling system can significantly reduce the risk of overheating. In Perth’s heat, adding a more efficient radiator can enhance airflow. A larger radiator with more fins allows for better heat dissipation, keeping the engine cooler.
Also, consider installing a high-performance fan. A fan that moves more air assists in lowering engine temperatures quickly. Regularly cleaning the cooling fins and ensuring there is no debris blocking airflow is equally important.
Lastly, checking the quality and quantity of coolant is essential. Replacing outdated coolant with a higher quality type can improve the cooling effect under extreme conditions.
Monitoring with an EGT Gauge
Using an Exhaust Gas Temperature (EGT) gauge is beneficial for monitoring engine health. An EGT gauge measures the temperature of exhaust gases, helping identify overheating issues before they become serious.
When temperatures rise too high, it indicates the engine is working harder than necessary. Ideally, operating temperatures should stay within a safe range.
Installing the gauge involves placing a thermocouple in the exhaust system. Regularly checking this gauge allows for immediate adjustments, helping to avoid potential damage from overheating. This simple tool can extend the lifespan of the mower and maintain performance during hot days.
Optimising Power Output
Efficient power management is vital for a healthy lawn mower. Regular maintenance is key. Changing the oil and cleaning the air filter can enhance performance.
Fresh oil reduces friction. This allows the engine to run cooler and more efficiently.
You can also adjust the carburettor to optimise the fuel-air mixture. Proper tuning ensures the engine gets the right amount of fuel, reducing the chance of overheating.
Another important aspect is using high-quality fuel. Poor fuel can lead to less efficient combustion, raising engine temperatures. Choosing a fuel that meets the manufacturer’s specifications helps maintain a cooler, more powerful engine.
