VW Carburetor Needle and Seat – 111-129-201 Ensure your fuel system operates at peak efficiency with this high-quality Needle and Seat Assembly. As a critical component within the carburetor's float bowl, this valve acts as the gatekeeper for incoming fuel. When the float reaches the correct level, the needle seats firmly to stop the flow of gasoline. A worn or debris-clogged needle is the primary cause of "flooding," which leads to hard starts, stalling, and dangerous fuel overflow. The 111-129-201 features a 1.5mm orifice, providing the ideal flow rate for stock and moderate performance air-cooled engines. This precision-machined brass valve is highly versatile, designed to fit a wide range of popular Volkswagen carburetors including original Solex, modern Brosol and Bocar replacements, and even performance Kadron setups. Replacing this valve is an essential step in any carburetor rebuild to ensure a steady, reliable idle and consistent throttle response.

Technical Specifications Part Number: 111-129-201 Size: 1.5mm Orifice Material: Machined Brass and Steel Installation & Maintenance Tips Float Level is Critical: The thickness of the washer used under the seat directly affects your fuel level. If the car stumbles on acceleration, you may need to adjust the washer stack to raise or lower the float height. Flush Before Install: Always flush your fuel lines before installing a new needle and seat. Even a microscopic piece of old fuel hose can get lodged in the valve, causing it to leak immediately. Inspect the Float: While the top is off, shake your float. If it rattles or feels heavy, it may have a pinhole leak and should be replaced alongside the needle and seat. Snug, Don't Strip: Carburetor bodies are made of soft pot metal. Tighten the brass seat firmly enough to crush the washer, but do not over-torque it or you will strip the threads. 8115150800 111129201 Show more
