DIRTY & DAMAGED? TIME FOR A NEW FILTER
In simple terms, the primary role of an air filter is to purify the air that enters your engine. This may sound like a straightforward task, but it's crucial for the engine's performance and longevity. Before air mixes with the fuel and ignites in the engine's cylinders, it must be clean. Unfiltered air is laden with various types of dirt and debris, which can be quite abundant, especially when you're mowing your lawn, kicking up grass clippings, dust, and more. Needless to say, you wouldn't want any of these particles infiltrating your engine.

So, how do you determine if your air filter has become clogged with dirt and needs attention?
- Power Loss: An air filter that's coated in dirt and oil can smother your engine, restricting the proper flow of air needed for efficient combustion. Reduced combustion power translates to decreased horsepower. If you notice your lawnmower struggling to maintain consistent power, it's time to inspect your air filter.
- Increased Fuel Consumption: If you find your engine burning through fuel more quickly than usual, a dirty air filter could be to blame. The engine tries to compensate for the loss of performance by consuming more fuel.
- Starting Trouble: An engine requires three essential components to start—air, fuel, and spark. If any of these elements are compromised, the engine won't start smoothly. A clogged air filter limits the airflow into the mixture, causing your engine to stall, surge, and sputter as it struggles to breathe.
Furthermore, if your air filter is damaged or has holes, you run the risk of allowing harmful debris to enter the carburetor, potentially causing severe damage to your engine.
So, when should you consider cleaning or replacing your air filter?
- Cleaning: Air filters can be cleaned if they're still structurally intact, with no tears or holes in the filter fibers.
- Replacing: If your air filter is soaked in oil, the filter material is torn, or there are noticeable cracks, it's time for a replacement.
Changing an air filter is a relatively straightforward task. Always consult your owner's manual for specific recommendations regarding air filter maintenance and replacement intervals.
By taking good care of your engine's air filter, you're not only safeguarding its performance but also extending its lifespan. So, when faced with the choice between rebuilding or replacing an engine or changing a dirty air filter, the latter is undoubtedly the more cost-effective and prudent option. Your engine will thank you for it.
