Solution is easy enough, remove the clocks and remove the front cover.With the clock faces exposed gently rotate the needle on the tacho to about 9000 it should then drop down to the 6 o'clock position.
If it doesn't drop to the 6 o'clock position but beyond it, remove the needle.
Do this by using 2 teaspoons to lever the needle off gently by placing the spoon sides facing upwards on either side under the needle near the spindle and levering it upwards.
Replace the needle, but set to the 6 o'clock position. Push the needle back on, but not too far on, ensure it is the same height from the face as the speedo.
