MK1 Gti mixture issue

Right my golf was running a treat today but it had a very slightly uneven idle… so i fiddled around with the mixture and now it wont work!!
Does anyone know what the mixture screw should be set to to get it running?

And yes i do feel like a twat

which screw the one on the throttle body or the one in the metering head?

oh i forgot to say

welcome to mk1 heaven :wink:

a bit of both!!
Mainly the one in the metering head i fear is the one i have messed up

Thanks for the welcome by the way

the throttle body one if you wind it out that increases the idle by letting more air in so make sure thats 3 to 4 turns out to start with then adjust the main mixture screw are the plugs soaking wet with fuel?

if so dry and clean then try and start :wink:

Havent had time to go in-depth as yet, was basically wondering if there was a start up mixture tweak i can do on the main mixture screw as i have totally lost count of where it is..

not really youd need a c0 tester to get it to where it should be however ive always managed to get it done by smelling the fumes and getting high works tho    

if you screw it down it will lean it up i belive been along time since i played with the k-jet system :wink:

Clockwise = richer.

If you're lean, you can squirt cold start into the air box to make it run
if you're rich, holding the throttle part open during starting will help

sorted, 4 turns down and a general fiddle and all is good.
Thanks for yuor help

no probs i was going to say im in brighton later i could have taken a look for ya :wink:

going to take a look at this myself over the next day or two. where are the two screws required to tweak to get the mixture a bit better??

btw is bens_cab the forum guru as he seems to answer most questions asked

no im just a mug a bored one

is your carb jon

it is mate.
wouldnt say your a mug at all - asked 2 questions in two days and youve been a big help with one, and hopefully a big help with this one as well

   

im crap with carbs    

your best bet is to get down an mot station and bribe them with beer tokens to set the c0 up on there machine :wink:

:-) they only trade in sheep around here mate, beer doesnt interest them - it just makes the ugly sheep a bit better looking  

so no ideas where the screws would be to adjust the mixture?

any pics of the carb ?

may be worth while posting a thread in big carb engine section

yeah and not the big block injection like i have done ops:

cheers mate
