u can try another new glow plug....maybe the problem of the glow plug....buy an OS A5 glow plug to try
By the way, based on "曲續果個位積油大多" and your video, your 油針 is too rich...
clockwise your 油針 approx half round to try again....if u can make a video record, please also take some shot on your 油針 and its componets
