Peter,
After logging in choose "Model Directory" in the left hand menu, then from the dropdown list "Please Select Model" choose "Ace". After that on the right hand side of the screen you will see Intro >> Pictures >> and Articles >> of which you choose the last option. Then it's the article at the bottom of the list "Solex Carburettor Service". [Click here] and it downloads and opens in PDF format. Enjoy.
Thanks a lot for your most interesting article on rebuilding the Bristol engine in ACtion.
Jerry
