.150 Alcohol Needle & Seat - Each

The Advanced Engine Design .150 Alcohol Needle & Seat is a precision fuel metering component designed for carburetors that operate on alcohol-based fuels, including methanol. This adjustable needle and seat assembly is suitable for various applications, including racing and recreational use, where precise fuel flow is essential for optimal engine performance.

Constructed from stainless steel, this assembly resists corrosion from alcohol's aggressive properties, ensuring durability and reliability. The 0.150-inch orifice opening is crucial for determining fuel flow rate through the carburetor's fuel bowl, allowing for proper stoichiometric balance in alcohol-burning engines that require richer fuel mixtures than gasoline.

Carburetor tuners and engine builders can benefit from this needle and seat assembly when replacing worn components or optimizing fuel delivery across varying load and throttle conditions. It is compatible with Holley and Quick Fuel carburetors, commonly used in both naturally aspirated and supercharged applications.
