The most common cause of a rebuilt speedo to fail early. The length of
most of the new cables are to long and will hit the inside mechanisim
on the speedo. The inner cable should only stick out 3/16 past the end
of the nylon piece that is pressed onto the cable.
Any more than that and you will damage a speedo.
