Artz cleaned the throttle and put something in.

When cleaning the throttle, something goes in and needs to be disposed of.

First of all, in order to prevent this thing from being sucked into the cylinder, it is best to remove this intake pipe and clean it.

If the throttle valve inhales hard objects and sundries, it will seriously enter the combustion chamber through the air inlet, causing the piston to jack up or the valve to get stuck. The fault is the lack of cylinder or abnormal engine sound. Another situation is that it is discharged by the exhaust valve in time.
