PURPOSE:To prevent overconcentration of mixture gas when a choke will function, by heating a bellows during cool time of engine thereby increasing the expansion of bellow previously and increasing the bleed air. CONSTITUTION:When the engine is cool and the cooling water temperature is lower than the setting temperature of a water temperature switch 142, said switch 142 will conduct to flow current from a battery 140. Consequently the contact of a relay 138 will conduct to supply current from the battery 140 to a heating member 136 thus to produce heat from said member 136. Consequently a bellows 110 is heated and expanded to displace a sleeve 124 to the right thus to increase camber of a reed valve 120 and to increase the bleed air, resulting in the overconcentration of mixture gas upon operation of a choke. |
