What's wrong with the sagitar trembling start?

There will be slight jitter when sagitar starts automatically, because the clutch differential has been engaged and the engine produces torque. Slight jitter is normal, but if the jitter is serious, it means there are problems, such as low idle speed, dirty throttle, dirty nozzle, serious carbon deposition in the engine, and poor working condition of spark plugs. First, check whether the throttle part of the engine is too dirty or whether the idle stepping motor is stuck. Or the gearbox locking valve is stuck, find a professional technician to clean the throttle or replace the stepping motor to eliminate the engine fault, and further determine whether there is a fault. You need professionals to determine the specific part of this jitter phenomenon. In general, the throttle valve is easy to get dirty or damaged.
