Buying advice

When choosing a carburetor cap, verify compatibility with your specific carburetor make and model, consider material durability (aluminum or steel for longevity versus plastic for weight), and assess whether you need additional features like fuel leakage protection. OEM caps provide exact fits but may cost more, while universal caps offer flexibility at a lower price.
