So I ordered a stage one kit from Huddersfield spares which I thought was a good idea. Once I received the kit I noticed that it did not come with a new needle or spring. I put on the kit anyway and used a friends upgraded spring. The only time that the car will run "like it should" is when you use full choke. This led me to believe I needed more fuel but my A/F ratio seems to be ok. Plugs are burning good and I used a color tester and according to the test I was running blue, which was good. I cant figure out what I need to do to make the car run like it should? Adjust the choke? or is it a matter of just tunning the carb until it runs right? Also at idle the car has a sound like there is an oversized cam if that makes sense, so very throaty. So basically I am lost on what to do. Any help right now is good help!!! Cheers!!

try the needle that should have come with the stage one kit

[Bks31589]

Yea thats the thing, it did not come with a needle or spring.

As above...sounds like you're too lean if you need the choke.
I think those kits usually come with an AAA or AAU needle.
What needle do you have installed at the moment?

[Bks31589]

its the same stock needle that was in the carb which i believe is an HS4. Simply because they didnt send a new one with the kit

Yes, you need a new one. But I guess you suspect that as you expected to receive one.

[stretch tech]

the needle for the stage one kit has a different profile to the standard one and is probably what is causing it to run lean...as above, i think it should be AAU but i'm not sure

Yes...but what needle??...need the number.
Take it out , read the letters on the top part of the shaft
Regardless...you'll need a richer needle most likely

I ordered the AAV which according to minisport is the needle needed for the stage one kit, sound right?

[Spitz]

AAV will be too weak

Thanks guys, ill let you know if this fixes the problem

AAu should be fine, best option is AAA + red spring.
