What types of components are covered under the emissions-related warranty?

The emissions-related warranty specifically covers any part whose primary purpose is to control emissions. This includes components such as catalytic converters, exhaust gas recirculation (EGR) valves, and fuel metering controls, which are designed to reduce harmful emissions from the engine. These parts are crucial in meeting environmental regulations and ensuring that the engine operates within the specified limits for pollutants.

This warranty is crucial for manufacturers and consumers alike, as it protects the consumer’s investment in their small engine by ensuring that the parts designed to mitigate emissions remain functional and effective. Any failure of these parts typically falls under this warranty, which reflects the manufacturer's commitment to complying with environmental standards.

In contrast, options that focus on parts not related to emissions, or components that solely aim to enhance engine efficiency or horsepower, do not fall under the emissions-related warranty. These items, while important for engine performance, do not directly contribute to controlling emissions and therefore are not covered by this particular warranty.
