ance complaints are, in many instances, caused by the
presence of dirt, water, gum and varnish caused by stale
fuel from prolonged vehicle storage, or other foreign
matter in the carburetor. To aid in diagnosing the cause
of the complaint, the carburetor should be carefully
removed from the engine without draining the fuel from
the bowl. The contents of the fuel bowl may then be
examined for contamination as the carburetor is
disassembled. Check filter.
