I have an old sun auto tuneup kit form the late 70's.
Some years ago the analog tach movement became jerky. I am thinking either the bearing for the indicator needle is either dirty or the lube has dried up.
I am thinking of cleaning the movement with quick dry electronics cleaner from the auto parts place. Methane, n-Hexane, Isohexane and some petroleum distilate. Claims no residue.
Has anyone ever cleaned or lubed a an analog meter ?
