Default Sticky Tach

1968 tach goes up slow and returns slow, sometimes it goes up to the last rpm and sticks there but after driving and get some heat in things it seems to be OK or maybe a hair slow. I don't think its a lube issue but I could be wrong. If I reach under the dash and pull the housing with the slightest and I mean slightest pressure the tach drops fine. The cable is making no noise. Could the housing be a hair to long or or the screw nut on the back be a little to tight.I think if the cable was to long it wouldn't change. If I just take the housing off ay the tach can I pull just the cable out, then push it back in, or will it not go back in the gauge that way. Has any one experienced this issue. Works sooner in warmer weather. Cable and housing are like new

Thanks

Did somebody try lubricating the cable on the tachometer end and got grease inside the mechanism?

No its been like that for years. That way when I got it.everything looks new. Speedo bounces a little to. I guess I will try to remove the inner drive cable from behind the gauges, if I can get them out that way. Clean them and use some graphite cable lube on them about a foot away from the gauges down ?

I think I will dry slide, its made for motorcycle cables. and maybe try to get a small shot of wd40 to the back of the gauge.

I wouldn't try that....or I'd make sure it was a VERY small shot. From what you've said---it sounds like something is in a slight bind--maybe slightly loosen the cable collar at the back of the tach like you said.
