Hi Stingray, sorry for slow reply, not been on Ribnet for a couple of days.
I have looked at the guages that are white with black numbers, they have "MZ" (but the Z is written backwards ) at the very bottom of the dials.
They are the same as the white dials on page 5 of the link bellow
I have also loaded the video clip of the engine on muffs on the drive on to You tube so anyone can watch it.
Any more questions the give me a call 07533568563
