Upgrade your carburetor to a big bore carb for added performance!

This has a modified throttle shaft pre-installed for maximum compatibility. This is the carburetor recommended by Zenoah for upgrading your engine. Engines with the stock carburetors tend to experience a lag in low-end acceleration when tuned for peak power. This carb includes an internal acceleration pump to allow faster recovery as throttle increases.
