Hafei Lubao engine fault light is on, the throttle is too big, and sometimes it won't catch fire. What's the problem?

Maybe the mixture around the spark plug is too rich.

When the cold machine is started, most of the injected fuel is in liquid state. Too much liquid fuel will flood the spark plug, but the liquid fuel will not burn. Therefore, it is necessary to avoid the overflow of spark plugs and fuel supplies. Stepping on the accelerator will increase the air intake, dilute the fuel around the spark plug and reach the ignition limit, so it can be started. If the car is an EFI car, do the following checks: Is the throttle dirty? The dirty throttle leads to insufficient air intake. For EFI vehicles, stepping on the accelerator is actually to increase the throttle opening. As soon as the throttle was turned on, the air intake increased and the car hit. In this case, clean the throttle valve.

Whether the fuel system is dirty. This is easy to understand. The oil circuit is not smooth. You need to give enough oil to light it. Check the oil circuit first, and then check the gasoline pump.
