Frequently Asked Questions

Q: Is this throttle slide legal for all Briggs LO206 classes?

A: Yes, this is the standard unrestricted black throttle slide required for all adult LO206 categories, including Senior, Masters, and Super Masters. It is not for use in Junior or Kid Kart classes, which require restricted slides.

Q: How do I know if my throttle slide needs to be replaced?

A: You should inspect your slide if you notice inconsistent throttle response, "sticking" during operation, or visible scoring on the surface. Because the slide dictates airflow and fuel-air atomization, any wear or binding can negatively impact your engine's performance and jetting consistency.

Q: Does this slide require any special tools for installation?

A: No special tools are required. It is a direct OEM replacement for the PZ carburetor. Simply remove the top cap of your carburetor, carefully remove the old slide, and swap it with the new one, ensuring the needle is properly seated and the slide moves freely within the bore.

Q: Will this slide improve my engine's top-end speed?

A: This slide is designed to provide the maximum, unrestricted airflow allowed by the rulebook. While it doesn't "add" horsepower beyond the engine's design, it ensures your engine reaches its full potential by eliminating vacuum leaks and airflow restrictions caused by worn or incorrect components.
