Identifying the Smoke Color and Its Causes
The color of the smoke your lawn mower produces offers a useful hint towards diagnosing the problem. The hue of the smoke can range from black, blue, or white, each indicating different underlying issues.
Black Smoke
Black smoke coming from your Bad Boy mower usually indicates an engine problem, typically caused by a clogged air filter or fuel-related issues.
A dirty or clogged air filter can prevent sufficient airflow into the carburetor, leading to an excess of gasoline and black smoke.
To prevent smoke emission resulting from a clogged air filter, keep it clean and consider replacing it more frequently when mowing in dry, dusty conditions. Starting each mowing season with a new air filter is also a good practice.
If black smoke continues even after you’ve replaced the air filter and adjusted the carburetor, you might need to take the mower to a repair shop.
A professional mechanic can diagnose the issue and determine if there are any other air restrictions or underlying engine problems that need to be addressed.
“I recently had an issue with my Bad Boy mower – it started emitting black smoke every time I used it. Recalling an article I read about mower maintenance, I checked the air filter first. Sure enough, it was clogged with dust and debris, a common issue here in Texas. After cleaning it, the smoke reduced but didn’t completely disappear. The article had mentioned that persistent black smoke might indicate a carburetor problem. Not confident in adjusting it myself, I took the mower to a repair shop. A quick carburetor adjustment there, and my mower was running smoothly again. That article not only helped me identify the problem but also saved me from potential mower damage.”

Blue/White Smoke
Blue or white smoke from your mower often indicates oil burning in the combustion chamber, which an overfilled oil reservoir can cause, oil spills during maintenance, damaged piston rings, valve train problems, or leaks in the engine gasket.
Another possible reason is oil being forced into the cylinder from a clogged air filter. When inspecting your mower, look for signs of oil burning off around the muffler or engine, possibly due to oil leaks or spills that occurred during an oil change.
If you find the oil level is too high, drain the excess and refill the reservoir to the appropriate level, using the dipstick for accuracy. It’s important not to leave excess oil on the engine but to let it naturally burn off.
If these measures don’t stop the blue or white smoke, you should take your mower to a repair shop for a more comprehensive diagnosis and professional repair.

Repairing or Replacing Damaged Parts
Damaged components in your mower, such as head gaskets, piston rings, or pistons, can lead to the emission of blue smoke, signaling that oil is being burned in the combustion chamber.
Promptly identifying and rectifying these issues is crucial to avoid further harm to your mower. Taking steps to repair or replace damaged parts, especially piston rings, is key in resolving the issue of blue smoke.
To prevent your Bad Boy mower from smoking and ensure its efficient operation, it’s important to regularly inspect it for any damaged components and address them as soon as possible.
If you find yourself uncertain about how to conduct repairs or replacements, seeking help from a professional mechanic is the recommended course of action for accurate diagnosis and effective repair.
Cleaning and Replacing Air Filters
A clogged air filter in your mower can lead to engine damage and cause your mower to emit smoke. It’s essential to keep the air filter clean and in good working condition to prevent these problems.
To change the air filter in your Bad Boy mower, first find the air filter housing. Then, take out the old filter and replace it with a new one. It’s advisable to replace the air filter at least once every mowing season or after every 300 hours of mower operation.
By regularly cleaning and replacing the air filter in your mower, you can help avoid engine damage and prevent smoking. This simple maintenance task is key to maintaining optimal performance and prolonging the life of your mower.
Checking Coolant Levels and Cooling Fins
For preventing overheating and smoking in your Bad Boy mower, it’s vital to maintain correct coolant levels and keep the cooling fins clean.
Regularly checking the coolant levels, ideally before each use or at least once a month, is a proactive measure to spot and address potential issues early, preventing damage.
Equally important is the cleaning of cooling fins. Over time, debris and grass clippings can build up, hindering their effectiveness and leading to overheating.
By routinely monitoring coolant levels and ensuring the cooling fins are clean, you can help avert overheating and smoking, thereby maintaining the optimal performance and prolonging the lifespan of your mower.
When to Seek Professional Help
If the smoke issues of your mower persist, or if you are uncertain about how to fix them, it may be the right time to consult a professional.
A professional mechanic can diagnose the underlying issues and provide you with the necessary guidance and repairs to get your mower back to its best. Ignoring persistent smoke issues can lead to:
- Additional damage
- Decreased performance
- Potential safety risks
- Invalidation of your warranty.
Do not hesitate to consult a professional mechanic if you’re experiencing any of the signs mentioned earlier, such as frequent smoking, difficulty starting, or loss of power.
They can help you address the problem with Bad Boy and ensure your mower remains in top-notch condition.
