Accelerator Pump Discharge

  1. Ensure float bowl and pump passages are full. Place carburetor over a clean container, and operate throttle 10 times from full closed to full open. Discharge should measure .25-.42 oz. (7.5-12.5 cc).
  2. If fuel discharge measures less than .25 oz. (7.5 cc), check for a clogged discharge nozzle, leaky diaphragm, improper pump stroke, faulty discharge needle and seat or discharge hose.
