Hi, Additya and the usual suspects are:
1. Throttle cables misaligned or misrouted.
2. Damaged or restricted fuel tank venting system.
3. Intake system air leak.
4. Vacuum piston malfunction.
5. Pinholes or torn diaphragm.
6. Accelerator pump leaking or no output.

8. Fuel level in bowl too low.
9. Restricted fuel supply passages.
