Maybe grease has got into the speedo head from the drive cable.

This could allow the spinning magnet to drag the needle a bit.

 

It's not easy to think of things that make the reading be too fast.

Too slow has obvious causes.

 

By the way I have a genuine Smiths drive that should work fine.

Came to me with a broken wire and has my 3mm key-steel fix for this.

It's like the one I did for Neil.

 

Also the Smiths originals are so much better than the repros I will buy any broken ones

and try to rebuild them.

These are all original Smiths. In most cases the wire-stub was rotating in the bevel-gear.

This is a common failure mode.

 

I have replaced this wire-stub with 3mm key-steel as discussed on this topic:

I would be interested in purchasing one for a 1973 MGB, which is currently and repeatedly eating the cheap angle drives available from Moss.

How can I contact Alan Taylor?  I found this site because my 73 MGB has the same issue.  replacement angle drives fail pretty quickly...
