Hello fellow 7ers,
This is my first post, though I have been reading the forum since June last year. I bought a 1937 Austin 7 AAL Open Road Tourer in May 2019 which had been in storage in South Australia for a few years. I had it shipped to Melbourne and got my mechanic friend Barry to look her (Tinkerbelle) over. On his advice I replaced the kingpins and track rod ends and brake cables. A few other things needed to be fixed such as the indicators and fabricating a new drive shaft for the windscreen wiper. I obtained a roadworthy certificate in January and the car is now registered in Victoria. This week Barry and I checked the tracking and found that it was toeing out by about half an inch. That could account for the twitching of the steering which is now much improved since we corrected this. Now I have turned my attention to the speedometer which is very erratic. If I drive at a steady speed of, say, 30mph the needle flicks up to 45 to 50mph every few seconds. Using a sat nav the 30mph is probably the correct speed. I have disconnected the speedo cable and cleaned it. When I reconnect it to the speedo gauge and put a battery dril onto the gearbox end the same error occurs so I assume that the problem is in the gauge rather than the gearbox or cable. I would be grateful for any suggestions as to the nature of the problem and how to fix it.
