I need to raise the idle in my car but for the life of me can't find the idle screw. Setup is twin 1.5 inch SUs. A picture would be really helpful. Thanks

There is some info here. http://sucarb.co.uk/technical-hif-type- ... ning-multi
You really need to make sure the throttle butterflies are at the same position and using the hose in the ear is a good way of checking.
No5 is the idle adjusting screw but to do it properly the interconnecting levers need to be backed off before you start then readjusted correctly afterwards.

Thanks for that
