Regarding the Morimori's Golf, the idling was unstable. :-(
So I got the used idle stabilizer.
Oh ! It is dirty !!
So I polished it ! :D
I sanded with "800 grit paper". After that, I polished it using the compound.
Is it like a new product ?! :D
Of course, I cleaned the inside of the stabilizer. (I used "carburetor cleaner".)
And I replaced.
loosen a band and remove the pipe of rubber. (Yellow circle)
Remove the connector. (Blue circle)
Remove the black rubber band. (White circle) Please note that this rubber band tends to break.
I cleaned the inside of the stabilizer many times. It is important, I think. Finally, I sprayed the inside of it with lubricant .
I could get the stable idling ! :D If the idling is unstable, please try to clean the inside of the idle stabilizer.
