Hey guys, i have a 13b bp with a weber 48 ida and its currently idling around 1000rpms, i spoke to my mechanic who has just finished tuning it about increasing the idle, he said for me to adjust the screw. Now ive spent awhile now trying to find diagrams and info about the ida but cant seem to find one that points to the correct idle adjusment screw,

anyone got a picture or diagram of where it is located? dont want to start adjusting the wrong one

Cheers
