Hawk 250 shift linkage not engaging

[Bamboozle146]

Hello, I've just bought a Hawk 250 secondhand from someone, and the shift linkage/bottle opener looking device isn't properly engaging the detent/star gear to properly shift.
We thought we had fixed it, but I took it down the road and it just missed the detent again.
Everything is tight, and looks exactly as it should.
You can also see the PVC spacer I made next to the shift lever in attempt to pull the shift tab closer to the detent.
It IS ENGAGING in the video, but again when riding, it just falls back off and grazes the detent/star gear.

Any help is greatly appreciated.
