Many thanks for your input.
Barrie, I do think the uprights are fitted the correct way. Both sides have a positive caster of between 3 and 4 degrees. So hopefully no insult to the old lady (31!).
I will definitely try to let the peg sit with less force and see if that changes matters. I have also enclosed an image of the worm. Maybe hard to see but there is some wear, especially in the center of the worm. I do think my worm Is just worn, maybe from historical over tightening?
Regardless I do think that the modern Michelin X’s are rather different to the older ones. First of all the later versions have an almost 20 mm larger diameter, different thread pattern and probably a different rubber specification. I definitely feel a large difference to the older ones when cornering, the new type sticks to the road much, much better.
Robin, I have had some contact with the Marles company. I can see on their website that they have restored a number of the Bishops boxes for AC’s. Do you or anybody else on the forum have any first hand experience with them and the quality of their work?
A last thought I have is that toe in should play a large part as well. 31 is set up with roughly 0,25 degrees per side, which should equate to the 1/16 inch as it says in the handbook. Anybody with different opinion/experience concerning toe in? I run the car with the original 16 inch wheels.
Thanks again.
Jonas
