This simple upgrade won’t cost much but can make a huge difference in your lawnmower’s performance. Additional tips to consider:

  • Upgrade to a high-performance spark plug. This ignites fuel faster, improving engine acceleration.
  • Install a smaller pulley ratio for higher blade speed. This will raise engine rpm for better cutting efficiency.
  • Use premium fuel instead of regular gas, as it has additives that enhance combustion and reduce carbon buildup.

These minor improvements can make a huge impact if done right. Boosting engines doesn’t mean you have to empty your wallet – just take the necessary steps mentioned above to give your machine extra power and get tasks done quickly and effectively. Finally, install a performance exhaust system to boost your mower’s performance and make your neighbours envious (and maybe a bit annoyed).

Installing a Performance Exhaust System

Want to increase your mower’s engine speed? Fit a performance exhaust system! Here’s how:

  1. Gather the tools – socket set, pliers, and safety glasses.
  2. Use the socket set to remove the existing muffler and exhaust pipe.
  3. Attach the new performance exhaust pipe to the engine’s manifold.
  4. Slide on the new muffler, then use pliers to secure it.
  5. Check for any gaps and adjust if needed.
  6. Test the mower for faster speed!

High-flow pipes and mufflers provide great ventilation for the engine, making it run cooler and more powerful. This means more acceleration and higher horsepower. Makes mowing quicker and easier!

Give your mower a boost with a high-performance air filter – like a shot of energy to the carburetor!

Replacing the Stock Air Filter with a High-Performance Air Filter

Replacing a lawn mower’s stock air filter with a high-performance one is a great way to boost engine speed. First, identify the location of the combustion air filters in the mower. Then:

  1. Disconnect the spark plug wire.
  2. Remove the old air filter.
  3. Clean any debris, dirt, and dust.
  4. Insert the new filter.
  5. Tighten all fixtures and re-connect the spark plug wire.

High-performance air filters are designed for more cool and dense air intake, which can improve fuel efficiency and power output. Replacing the normal paper air filter with foam can allow more clean air to flow through, increasing mower HP.

It’s important to check if the biodegradable filters are authorized by your local environmental board.

One client, Allan, modified his mower to be more productive. He replaced his old stock with an ultra-high airflow-low strain biodegradable element.

Be careful when revving the engine though, or your mower might take flight!
