I think he was meaning he drilled a hole in the plate that had been added behind the speedo.
Regarding the speedo I would start by checking the cable.
*undo from back of speedo
*check the inner cable cannot turn or slip, i.e. that it is engaging down at the gearbox end
*withdraw the cable inner from the outer
*hold the inner by both ends so it forms a teardrop shape with the ends about 10cm apart and twist. If the inner is OK it should turn without jumping, if it jumps or kinks it prob needs replacing. Check general condition of the inner.
*If it's OK grease with molly grease but wipe away the grease from the top 20cm to prevent grease entering the speedo.
*Check the route of the outer that it takes no sharp bends before refitting too the speedo. Try it without the plate to begin with.
Another experiment would be to disconnect the cable at the gearbox and carefully run the speedo cable with a drill to check the speedo does actually work. May need to go in reverse can't remember) But the gearbox end is notoriusly hard to reach unless you are a contortionist with tiny hands.
