How to step on Pentium b50 after changing solar terms? How can you only run 60 kilometers an hour without electricity?

Is the clutch plate burnt out? I need to go to the store to check it out.

In addition, recall whether there was a big throttle and a semi-clutch in the driving process before this.

In addition, check the throttle, throttle position sensor and ignition coil. Conduct an investigation.
