General information about this item

Product info
Mixing tube No. 10, with part number B7-03-044, controls the precise metering of fuel and air in the BMW 700 carburetor and is therefore crucial for smooth engine operation. During restoration, worn or modified mixing tubes should be consistently replaced, as even minor deviations in the bore diameters significantly affect the fuel-air mixture. A correctly calibrated mixing tube is essential for achieving the BMW 700’s original performance and fuel consumption characteristics.
