It\'s just an air bleed screw, not an air/fuel mixture screw by the way. But i\'m sure you knew that! ;) :p

lol i didnt know exactly what it was if im honest. someone else thought it may have been a fuel mixure which is where i got that from. you learn something new every day :) lol. so if i screw this fully in it will cut the engine out (Providing i dont have an air leak)?

No necassarily: this also the idle adjustment screw on the front of the throttle body. If both that and the air bleed valve are fully screwed in, then yes, you\'ll get a stall (When warm - i think the cold start will keep it going when it\'s not up to temp)

if you have solved it then it should idle smoothly and not hunt as a starting point!
