3-8 FUEL SYSTEM Throttle Control Cable
The throttle control cable is actually an assembly of three cables: the throttle cable, the carburetor cable, and the oil pump cableThe throttle cable runs from the throttle lever to the cable assembly junction where it connects to both the carburetor cable which leads the throttle valve, and the oil pump cable which leads the oil pumpSince the throttle lever controls both the throttle valve and the oil pump simultaneously, it is important that each cable be adjusted to its designed base position so that the oil and air mixture reach the engine in the correct proportion at all throttle openingsCable stretch creates excess play at the throttle lever and alters the base positions of the cables at the throttle valve and the oil pump, necessitating periodic adjustment
