| + | The check valve is press fit into the bowl (yellow circle below) and has two main functions. | ||
| + | - It feeds gas to the accelerator passage in the bottom of the bowl. | ||
| + | - It seals off the main fuel supply between the bowl and the accel pump passage when the pump is actuated. | ||
| + | |||
| + | The disc is left loose by the tabs in the normal relaxed state to allow gas to enter the accel passage below. \\. \\ | ||
| + | Then it is seated when the pump shaft is actuated by way of pressure created in the accel passage of the bowl which pushes the disc up into the seat. \\ | ||
