  • Page 82 General theory DIAPHRAGM AND PISTON OPERATION The carburetor is a variable-venturi type, whose venturi cross sectional area is increased or decreased automatically by the piston valve . The piston valve moves according to the negative pressure present on the downstream side of the venturi A. Negative pressure is admitted into the diaphragm chamber through an orifice provided in the piston valve .
  • Page 83 SLOW SYSTEM This system supplies fuel during engine operation when the throttle valve is closed or slightly opened. The fuel from the float chamber is metered by the pilot jet where it mixes with air coming in through the pilot air jet .
  • Page 85 MAIN SYSTEM As the throttle valve is opened, engine speed rises and negative pressure in the venturi A increases. This causes the piston valve to move upward. The fuel in the float chamber is metered by the main jet . The metered fuel enters the needle , mixes with the air admitted through the main air jet and forms an emulsion.
  • Page 86 AUTO-ENRICHENER (AUTO-CHOKE) SYSTEM The automatic enrichener (automatic choke) device consists of the PTC heater A, the thermo-wax B and the plunger/needle . When the thermo-wax B is cold, the plunger/needle moves upward, Fuel is drawn into the enrichener circuit from the float chamber Enrichener jet meters this fuel, which then flows into fuel pipe and mixes with the air...
  • Page 87 FLOAT SYSTEM The float and needle valve work in conjunction with one another. As the float chamber the float rises and the needle valve pushes up against the valve seat. When this occurs, no fuel enters the float chamber . As the fuel level falls, the float lowers and the needle valve unseats itself;...
  • Page 88 ACCELERATOR PUMP SYSTEM This system works only when the rider opens throttle grip quickly as pump send the necessary amount of fuel to the carburetor bore for correcting fuel/air mixture ratio. When the rider open the throttle grip quickly, the intaken air volume becomes large and air velocity at the bottom of the throttle valve (piston valve)is slow and sucking volume of fuel is less.

  • Page 113 BATTERY CONSTRUCTION PGO sscooters uses an MF (Maintenance Free) battery. As shown in the right illustration, the battery consists of electrodes, separators, safety valve, filter, etc. Fine glass fiber is used for constructing the separator which holds electrolyte inside. When a discharged conventional open type battery is re- charged fully, lead sulfate turns to lead dioxide and sponge- like lead.
  • Page 114 Insert the nozzles of the electrolyte container into the battery’s electrolyte filler holes, holding the container securely. ! CAUTION Take precaution not to allow any of the fluid to spill. Insert the nozzles squarely to the battery. Check that air bubbles are coming up from each electrolyte container and leave in this position for more than 20 minutes.
  • Page 115 PRECAUTION FOR HANDLING BATTERY The battery produces combustible gasses and therefore can explode if handled improperly. Use Caution for the following in addition to general service precautions. Never allow the battery to short-circuit. Keep away from sparks and fire. Charging of the battery must be operated in an open and well ventilated area and never operate in an closed indoor.
