HOW TO: Install 9558K Float hinge pin
Note: Picture to be used for reference only. Carburetor models may vary.
Note: Please read all the WARNINGS below.
WARNING! Before any work is carried out, the carburetor should be dried of any fuel as gasoline and gasoline vapors are very flammable. Check for and remove any gasoline or other fluids and loose parts, especially before turning the carburetor upside down to check float level (see below).
a) Disconnect the accelerator pump rod (3) from the ball sockets at each end. Remove the choke lever fulcrum screw (1) and disconnect the choke valve tension spring (14) using the pliers. Remove the five airhorn screws (31) and their lock washers. Lift the airhorn (32) off, with the accelerator pump (10) attached, carefully pulling the accelerator pump leather through the airhorn gasket (20). Unscrew the float hinge pin (49) and remove from the bowl casting.
b) Holding the float at the hinge end, install the new hinge pin into the casting, capturing the float hinge. Tighten the float hinge pin into the casting. Now is a good time to check the float level.
CAUTION! For reasons of customer safety, we do not recommend that the fuel level in your Stromberg carburetor is set ‘wet’, measuring the level of fuel in the bowl. We recommend setting the float level ‘dry’, as we do at the factory with excellent results.
c) To achieve the correct fuel level when the carburetor is in use, simply adjust the float hinge to ensure that the float sits level in the bowl when the inlet valve is fully closed. By ‘level’, we mean that the top surface of the float should be parallel with the top edge of the casting (not at the same height) and not pointing up or down at either end. The simplest way to check this is to hold the carburetor upside down and eye the float through to check it is parallel with the edge of the casting. Adjustment is made by bending the vertical part of the float hinge where it contacts the ball in the end of the Stromberg S-Jet (or the needle in the traditional needle valve). Holding the horizontal part of the hinge with the pliers to prevent bending the body of the float, move the vertical part of the hinge away from the float body to lower the fuel level and vice versa.
d) Replace the airhorn and other parts in reverse order, taking care not to wrinkle the accelerator pump leather washer or catch it on the slot in the accelerator pump well. Use a new airhorn gasket (20). Tighten the airhorn screws (31) to 5in./lbs. minimum.

These instructions, warnings, cautions, and notes are limited to replacement of the parts named in the Service Kit. Stromberg has separate instructions for carburetor rebuilding, installation and setup.
WARNING: Before working on any carburetor, it should be removed from the car and dried of any fuel as gasoline and gasoline vapors are very flammable. Never smoke, use an open flame, or produce any sparks where gasoline or gasoline vapors could be present. Doing so may cause a fire or explosion, resulting in property damage, serious personal injury, or even death.
WARNING: Always perform any work on the fuel system in a well ventilated area. Failure to do so may result in the build up of dangerous gasoline or other combustible vapors that may cause severe respiratory injury, or a fire or explosion, resulting in property damage, serious personal injury, or death.
WARNING: A thorough knowledge of carburetor function and repair is required. Therefore, Stromberg recommends that rebuilding and installation be performed only by a professional auto mechanic. An improperly rebuilt or installed carburetor may cause poor performance or lead to property damage, personal injury, or death, and may void your warranty.
WARNING! When replacing the carburetor onto the engine, always ensure you have connected all of the linkages – throttle, choke, accelerator pump – and fuel lines correctly. Manually operate the throttle lever and choke mechanism to ensure free movement. Any sticking, binding, or ‘over-center’ movement in the linkage could result in uncontrolled engine speed, property damage, serious personal injury, or death.
While the individual parts in this Service Kit are covered by the Stromberg Carburetor Limited Warranty, the use of this Service Kit does not guarantee that the rebuilt carburetor will deliver correct performance and economy.
