Re: Unleaded petrol

In some of my Ariels, various old tank coatings have dissolved. They’re either rubbery or hard chunks, depending on the coating. The only solution, as Roger wrote, is to remove them and apply a modern, ethanol-resistant coating.
By the way, I run all my Ariels on E10 without any problems.

Re: Avon tyres, lack of

This year I fitted three Heidenau tyres. I usually do this myself on the workshop floor. This time, it only worked with a machine, two people and an incredible amount of effort. Somehow the wires are significantly shorter than on Avon or Barum tyres. As I wouldn’t stand a chance of repairing a ...

Re: Replacing RH cover on BA gearbox on VH

During assembly, the sector must be fitted into the gearbox housing. Only then can you see both marks and align it correctly.

Re: Square four Mk1 rocker

Duncan,
check which oil you're running.
It should have a high flamepoint.
For example and with good experiece I would recommend this MOTUL 3000 20W-50 4T 240.0 °C / 464.0 °F

I'm still breaking in the 37 4G. I've just worked on the pistons for the third time, and they seems to be working, but I have some questions about the gearbox and oil valve.
How do I ...
