hi im new to this site and im after a bit of help sorting my s2 out when i start it it revs up and down on its own why i dont know and secondly could someone help me with the boost pipes that come off the amal valve where they go to as i bought the car to restore and put right the amal valve was removed and an adjustable boost thing put it and i want to put the amal valve back on any help would be much appreciated
thanks

 

Reving up and down at idle is normaly your idle mixture out, Amal valve should be plumbed in like this:

 

hi thanks going have a go tomorrow and thanks for the diagram its going be a big help also how do i adjust the idle mixture or is it better taking it a garage
thanks

 

damn karlos was in there quick :P lol, as far as the mixture goes mate i would advise taking it to a garage but if u do get brave, or some people would say silly lol. then its located ontop of the metering head, it will either be a long thin tube kinda thing or a screw that you have to remove, once removed u then stick the correct sized allen key in the hole and adjust it, i think its clockwise to lean the mixture and anti to richen, but not 100 percent buddy

 

lol

Clockwise to Richen, Anti to lean out, try one way 1/4 of a turn at a time if it gets better then great if it gets worse then try the other way!
Just play around until it idles nicely if you dont have a CO Meter, easy mate!

3mm Allen key after removing blanks, arrowed!
