HOW TO: Install 9563K Bowl plug gaskets

Note: Picture to be used for reference only. Carburetor models may vary.

Note: Please read all the WARNINGS below. 

NOTE: Stromberg bowl plug gaskets are usually replaced with the whole carburetor removed from the intake manifold. However, if you are experienced with Stromberg service and repair, and want to keep a multi-carb linkage in place, an alternative is to remove just the carburetor bowl and airhorn, leaving the base castings in place on the manifold. Always make sure there is no fuel remaining in the carburetor fuel bowl.

PARTS REPLACEMENT

a) Remove the three bowl plugs (48×2 and 43) and their gaskets (44) from beneath the float bowl.

b) Inspect the three plug gasket surfaces in the bowl casting for cuts, nicks or grooves. If anything is present that might prevent the gasket from sealing tight to avoid leaks, you may need to spot face the gasket surface to get a good fuel- tight seal. A trustworthy machine shop can do this for you. The cutter tool OD is 0.6inch. Inspect the three bowl plugs too. If they have chewed up slots, bad threads and/or poor gasket surfaces, replacements are available from your Genuine Stromberg dealer as kit 9522K.

c) With good gasket surfaces, fit a new ring gasket (44) to each bowl plug (48 and 43) and install them back into the casting. Take care to avoid cross-threading the plugs into the castings, especially the outer ones. And use the widest screwdriver blade you can, to avoid marking the slots in the plugs.

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.

WARRANTY
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.
