3. Installing Inline Fuel Filter
- What I Did: Added a fuel filter to the fuel line.
- Outcome: Kept the carburetor free from debris.
- Personal Experience: Extra layer of protection for the fuel system.
- Estimated Cost: $10 – $30

Extra tips
- Float Valve Wear: Over time, the rubber tip of the float valve can wear out, causing it to leak. Regular inspection can prevent this issue.
- Fuel Quality: Poor quality fuel can contribute to carburetor issues. Using high-quality fuel can reduce the risk of contamination.
- Climate Impact: In colder climates, the choke is used more often, which can lead to richer fuel mixtures and potential overflow into the oil.
