To diagnose a bad accelerator pump, first inspect the pump diaphragm for tears or cracks. Then, while the engine is off, observe the throttle linkage as you manually operate it; a healthy pump should squirt fuel into the carburetor. If there's no fuel spray or it is weak, the pump is likely faulty and should be replaced.
