6.1.11.2.3. Productivity of the accelerating pump
The course of the accelerating pump can be adjusted, turning a nut on the end of draft of the drive of the accelerating pump. Data on productivity of the accelerating pump are provided in subsection 6.1.1.
| PERFORMANCE ORDER |
| 1. With the carburetor installed in the car, and removed by the air filter start the engine for several minutes in the idling mode, then switch off it. |
| 2. Looking in the carburetor diffuser, manually open a butterfly valve. When opening a butterfly valve the fuel stream from the accelerating pump has to appear. In the absence of a fuel stream, perhaps, the accelerating pump is faulty or channels of supply of fuel of the accelerating pump are blocked. |
| 3. This check defines only operability of the accelerating pump. For more exact check of the accelerating pump it needs to be removed from the engine. |
| 4. Fill the float-operated camera of the carburetor with fuel and install the carburetor over a measuring vessel. |
| 5. Ten times at an interval of three seconds completely open a butterfly valve. Measure amount of the fuel given by the accelerating pump, and compare it to the data provided in subsection 6.1.1. |
| 6. Check that the stream of the fuel given by the accelerating pump got on an axis of a butterfly valve. If necessary, being careful, turn in nozzles of the accelerating pump. |
