I tried several of the quick fix methods mentioned in regards to getting my tach to work.

They all seemed to work for maybe a day or two. It seemed that everything I put in there was squashed down to the point that there was no more spring or pressure being applied.

I got to thinking what could I put in there that would keep some spring. I decided to put rubber bands in the cylinder and snugged it down pretty good and it has been working ever since with no problems.
