E z turn. That looks like it.
Want to try it.
One fix was Teflon clear tape on the external side of the throttle shaft, but I can't locate any locally. I know bushings are good, just want to experiment. Had someone take a disliking to my silver soldered throttle shaft repair. All he heard was a poor idle.
Took him a year to bring it to my attention.
