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

Try lubing the cable. There's a product for this called Kable Ease:

The tach/speedo cables have to be removed from the instrument side, there are collars swaged onto them. To do this I had to dissassemble the entire dash to get enough room to reach in and disconnect the cables and pull them out.
The lazy way to address this is to disconnect the tach cable at the distributor, hold that end up and squirt some cable lube down the shaft, but any old grease, grime, etc. will still be in the housing. You can also use a drill motor to turn the cable as you add lube.
