Check whether the oil circuit is open, whether the tubing is choked or not, and whether there is foreign matter blocking. 2, the idle speed is too low: the new carburetor can not match the machine completely, and the old machine may need higher idle speed because of the aging or wearing of various parts.

Check whether the negative pressure hole in the red circle is blocked when it is installed.
