Throttle Fault of Tianlong 440 Gas Tractor

Due to insufficient tension of wire rope.

Solution: 1 Unscrew the fixing bolts and nuts of the air filter, open the filter cover and take out the filter, so that you can clearly see the opening and closing of the air valve driven by the steel wire rope.

2. If the bending amount of the wire rope is extremely small, it means that the wire rope is very tight. Even if the driver releases the accelerator pedal, the throttle cannot be completely closed, resulting in excessive fuel supply and extremely high waiting speed.

There is also an inspection method, that is, step on the accelerator pedal to see if the throttle can stand upright, that is, fully open, to judge the fault.
