Jet Flow Testing Setup

• I recommend flow testing and resizing jet, which have been soldered and re-drilled.
• These photos show my setup which pumps water up a pipe to obtain a consistent column of pressure. Water is measured into a beaker. For improved accuracy, the tube/jet should be held horizontally and not tipped down as shown in photo.
• To learn more about flow testing see "Zenith Model 'A' Carburetor Restoration Guidelines".
