I believe it's the old grease in the speedo that creates resistance on the cable. As the cable is effectively a spring, it winds up from the resistance and then it's wound up enough to then let go. This causes the speedo needle to jump faster. The cycle repeats.
Lubing the cable can help but it's usually the speedo needs a strip down and service.

This can be just a bit of debris in the space between the rotating magnet and the pointer drum around it. Often a mangled bit of spider.angrydicky wrote: ↑Sun Jun 04, 2023 8:50 am The speedo is pathetic though. At 'about 50' it's bouncing between 30 and 70. Any ideas on what might be causing this?

Re: Austin A70 Hampshire
Austin Counties Rally weekend - Part 1.
I packed a load of tools and spares in the car, checked all the levels and tyre pressures, brimmed the tank with premium fuel and headed for Derbyshire. From Coningsby to Sleaford, then along the A17 to Newark, then Mansfield, then Ironville to visit the chap I got it from, the previous owners nephew. He was delighted to see it again and said it sounded exactly the same as he remembered. He gave me some more spares he’d found for it too.
The A17 was fucked in both directions due to an accident, but despite the heat the A70 behaved itself. I did switch the engine off for the really long periods of idling.
Met up with some Counties club members in the evening for a drink and a buffet at the hotel.
That evening as I was heading back to my digs, it wasn’t running very well, wouldn’t idle, and stank of petrol, so I pulled over. Took the float bowl off and blew out some more crud which had made its way through. Blew out the jets. Checked the needle valve was free (which it was) and put it back together. Primed the fuel pump to fill up the float bowl, at which point I noticed petrol was squirting out of the joint between the pipe and carb, that was loose strangely, tightened that up and it fired straight up and was running better.
I’ve got the ideal room by the way!

Re: Austin A70 Hampshire
Great to see you parading the car back with Uncle Albert. I bet he was surprised! What size is the Hampshire in relation to moderns? I assumed it would be small, but the photo with the blue Vauxhall Grandad in the background suggests it's a bit more imposing than that. Unless it's a an optical illusion...

Re: Austin A70 Hampshire
It’s about the same length and width as my Rover 600 I would guess, but is tall. Very tall. Which means it isn’t dwarfed by the smaller soft roaders.
Off to the Great British Car Journey shortly. They have invited a few Austin clubs down for an Austin day in the car park.

Re: Austin A70 Hampshire
Enjoy your weekend. Nice selection of ancient Austins there, two from Holland I think? And another Hampshire, superb.

Re: Austin A70 Hampshire
Sorry, I knew I hadn’t updated this thread in a while but ten months is inexcusable. Anyway, here’s what I’ve been up to with the Hampshire.
The Counties rally went very well. On the Saturday, we did the Great British car journey in the morning, followed by an informal run around the Peaks or a visit to Longbridge Motor Spares (formerly Earlpart) I chose the latter. Dave who owns it has a fantastic selection of spares for BMC/BL and counties. That was followed by a lovely meal in the evening.
Sunday was the main show day at the Crich tramway museum.
In total we had three 16s, two Hampshires, three Herefords including a countryman and two Atlantics (both convertibles). We also had one Sports, one Dorset (which was driven to the rally from Holland) one K8, and a few Devons and Somersets.
It was a lovely weekend spent in the company of likeminded enthusiasts and I really enjoyed it. The ACCC members are extremely friendly and they were so excited to see the Hampshire there.
I was quite shocked when it came to the prize giving (voted for by members) and they awarded me the A70 Hampshire prize! It was more in recognition of my efforts to get the car to the rally under its own steam than the condition as it’s pretty atrocious and the other Hampshire there was in far better condition (though far from mint). I was chatting to the owner of that one for ages, a lovely old boy who has owned his Hampshire since 1970 (I think he said). It was the first opportunity I’ve had to see another one close up.
Shortly after leaving Crich, the heavens opened and I found myself driving a very old and not at all watertight car through some of the worst rain I’ve ever driven in. The wipers aren’t actually that bad on it but they couldn’t keep up with this rain, eventually it got so heavy I couldn’t see to drive any more and I was getting completely drenched from the water coming in through every seal, around the sunroof etc. I pulled over and a lady pulled over in a modern car behind me. I thought she wanted to enter the driveway I’d pulled across but it turned out she couldn’t see where she was going either, which gives you an idea of how heavy this rain was! I sheltered in her car for 20 mins or so before it finally eased off enough I could continue with the journey. Apart from water getting into one of the horns and shorting it so the horn kept randomly going off, I didn’t have any more problems. I pulled over and tied a bit of plastic from a shopping bag around it to try and stop the water getting in (it worked). I had to stop a couple more times when the rain picked up again but eventually I got home and put the car away in the garage to dry out. I was so glad the wiper motor held out as it hadn’t been used in anger since the 1980s and all I’d done was test it worked, opened it up and added some fresh grease.
