MG Midget and Sprite Technical - speedo calibration

Hi My speedo is overeading. Any recommendations for a suitable restorer/overhauler?


Thanks

Thanks David, I recall there was someone who took ages to respond I assume this is not him?

ISTR Dominic in Switzerland had a problem with him but many others have had good service, he's done two speedos for me with a 2 to 3 week turnaround.
I've just found an email addy too:

Richard took a while to get mine done too but in the end it was a spot on job, very accurate, and pleasant guy to deal with.

I discovered that you need to ensure there's no preload on the drive cable before fully installing it into the speedo head but I also worked out a very easy method to prevent this, remind me nearer the time and I'll look it up for you or just explain from memory (no!).

I rarely give a supplier a highly negative rating, but here I cannot do anything else. It took Richard Jenkins four months to do mine, and even then I had to return it for a second try because it was way off. In those four months I was given endless excuses (most of which were plain lies) and many (missed) delivery dates, and long periods of not answering the phone at all. I suggest there are many others that can do a better job, I now only use Speedograph Richfield. Talk to Tim. At least he is normally reachable unlike Richard Jenkins.

I used Speedograph Richfield for both speedo and tacho. Good service. The tacho read too fast and he spotted it was the cable preload, and with a new cable it's fine.

I also had very good experience with Richard Jenkins.

Joey will calibrate it. Mo-Ma does instrument restoration for clients around the world. They have all of the gears and bits.

I have had them repair and calibrate my Smiths MG speedometers as well as VDO Volvo KM speedos from S. America (both mechanical and electronic.)

I'd not use Speedograph Richfield again. It took them 4 attempts to overhaul my Elan speedo and it still didn't read accurately after all that.

Thanks for all the replies. A bit of a mixed bag of recommendations. Having spoken to Tim at Speedograph and Richard at C & V I sent it to Tim. He has advised a 3/4 week turnaround but given I can't use the frogeye because of lockdown its not a problem. Will report back on the results
Bob Beaumont

Assuming that tire size is correct and that speedo gearing is compatible, I have had luck removing the needle, taking the car up to speed with a helper and a GPS and reinstalling it while moving. Once stopped, a firm tap with a wooden mallet will keep it firmly in place.

If there is a gearing issue, of course your reading would not be linear after resetting the needle.
