摘要： A carburetor including a body having a main bore through which a fuel and air mixture is discharged from the carburetor for use by an engine a priming passage communicated with the main bore, a pump that moves fluid into the priming passage, and a flow restrictor received within at least a portion of the priming passage to reduce the minimum effective flow area of the priming passage. The flow restrictor has a body received at least partially within the priming passage so that fluid flows around the flow restrictor and between the structure defining the priming passage and the flow restrictor.

摘要： A purge and prime assembly for a carburetor includes a purge and prime pump that alternately takes in and discharges fluid, and a plurality of passages through which fluid is routed. The passages may include a purge passage through which fluid is drawn by the purge and prime pump, a return passage through which fluid is discharged from the purge and prime pump and discharged from the carburetor, and a priming passage through which a portion of the fluid discharged from the purge and prime pump is routed to a main bore of the carburetor. The assembly may also include a purge valve that prevents fluid from being discharged from the purge prime pump through the purge passage, and a return valve that prevents fluid in the return passage from being drawn into the purge and prime pump.

摘要翻译：一种化油器，包括具有主孔的主体，燃料和空气混合物通过该主体从化油器排出，以供发动机与主孔连通的起动通道，将流体移动到启动通道中的泵和限流器在启动通道的至少一部分内，以减少起动通道的最小有效流动面积。限流器具有至少部分地接收在启动通道内的主体，使得流体围绕限流器流动，并且限定了引导通道和限流器的结构之间。
