JAVENYIMAN Carburetor Tune-Up Kit for Briggs & Stratton 20–25HP Intek V‑Twin — Alloy Jets & Gaskets

A complete replacement carburetor tune-up kit designed to restore fuel-air mixing and reliable starting for Briggs & Stratton 20–25HP Intek V‑Twin lawn mower and tractor engines.

If your Briggs & Stratton V‑Twin engine—models like 40G777, 40H777, 44M777, 44P777 or 44S677—is showing rough idling, hard starts, or poor throttle response, a worn or clogged carburetor is often the cause. The JAVENYIMAN 796997 carburetor tune-up kit supplies high‑strength alloy replacement parts and consumables matched to the OEM family of carburetors so you can rebuild performance without replacing the entire carburetor.

• Includes jets and needles tuned for Briggs & Stratton 20–25HP V‑Twin models.
• New gaskets and seals stop vacuum leaks that disturb idle.
• Rebuilding saves cost versus buying a full carburetor assembly.
