The PGO BR-150 Bug Rider engine may only run when fuel is sprayed directly into the carburetor due to a fuel delivery issue. Possible causes include:

1. Clogged Fuel Line or Filter – A blockage in the fuel system may prevent fuel from reaching the carburetor.
2. Malfunctioning Fuel Pump – If the fuel pump is not operating properly, it may not deliver fuel to the carburetor.
3. Carburetor Issues – A clogged or faulty carburetor may not allow proper fuel flow.
4. Vacuum Leak – A vacuum leak may prevent fuel from being drawn into the carburetor.
5. Blocked Jets – If the carburetor jets are clogged, fuel may not mix properly with air.

These issues cause the engine to rely on direct fuel spraying into the carburetor for operation.
