STA-BIL Carb Choke & Parts Cleaner - 12.5oz

The STA-BIL Carburetor and Choke Cleaner in a convenient 12.5-ounce aerosol can is a proven solution for dissolving gum, varnish, carbon deposits, and dirt buildup inside carburetors and choke systems. This product restores engine performance by removing the fuel residue and oxidized compounds that accumulate over time—especially problematic in engines that sit for extended periods or run lower-quality fuel. The integrated spray nozzle with directional tube allows access to confined spaces where deposits hide, ensuring thorough cleaning of fuel passages and metering jets.

Once applied and the engine is run, STA-BIL carburetor cleaner dissolves varnish without disassembly in many cases, though severe buildup may require soaking or manual cleaning. The product helps restore cold-start reliability and smooth idle characteristics by clearing blockages in the fuel delivery system. A single 12.5-ounce can treats multiple carburetors or allows repeat applications on stubborn deposits. The aerosol delivery method ensures even saturation and reaches areas that brush or soak cleaning alone cannot access efficiently.

This cleaner is essential for anyone maintaining small engines, motorcycles, ATVs, classic vehicles, or equipment that's been stored or idled for months. It's particularly valuable when preparing vintage or collectible engines for use, diagnosing hard-start or rough-idle problems without pulling the carburetor, or performing routine fuel system maintenance. The product is also suitable for cleaning throttle plates, intake valves, and other fuel-contact surfaces in modern fuel-injection systems, though it's specifically formulated for carburetor applications.
