Can anyone tell me if this screw is used for adjusting a Leyland mini tachometer?
Mine is reading 4300rpm compared to 4000rpm on the new timing light.
I have a feeling that there is a smaller screw that is hidden behind the front face as well.

Hey Brad, I read your message btw, but have been away. I forgot to reply.

There is always a way to trim a tacho (Or just about any analogue instrument) because of internal changes due to manufacturing tolerances. It may be the pot you're looking at in the image you've put up, but I would need to have a look at it. I don't work with Leyland Instrument clusters really..

Ok thanks.
I will just play around with every adjusting screw I can find and see what happens.
