So, 30-odd years after fitting it in the dash, it occurred to me that perhaps my Smiths MA rev counter actually works? If only it was connected to something.

It's a 4:1 unit though, and while I'm familiar with the method of driving off the end of the distributor, if it won't indicate correct speed then I wouldn't bother.

I understand Ulsters ran the tacho off the front cam gear, in fact I've got an external photo of the connection; but this looks like something that wouldn't be easy to set up on a standard (3-brg) engine without a few special parts.

So my question simply - is there a relatively easy way to drive a mechanical 4:1 tachometer from a standard A7 engine and get the correct indication at the dial?

Shouldn't be too difficult to adapt one of these to drive from the bottom of the distributor shaft. http://www.gaggs.co.uk/html/tachometers.html

Talk to Speedograph Richfield. I think they have what you need.
