Hi
wander if any 1 can help. I've got a 1981 mini HL running bog standard 998 with a mini sport stage1 kit on it. I fitted stage 1 kit and had problem where it was running out of fuel at 60 mph! I have to turn mixture up so rich it struggles to idle and at idle it starts to flood but will run over 60 mph but still lean. I look at a post on minifinity which said it was the wronge carb needle and recommended an AAA needle or AAU needle. I brought both these needles from himley. I tried both needles and are too rich at top end. E.g flooding. The needle I got with stage 1 was an AAV.

Has anyone got any suggestions as to what needle would be best?

rolling road?

there was considering haveing it rolling roaded but it's finding one near me! As a mecanic I'd like to think I'd be able to get it right me self!

IMO a rolling road is a real must after fitting a stage 1 kit , it will ensure your fueling and overall set up are spot on , something you cant always get with a colourtune or similar

im after a rr session aswell. i found that after my stage one was fitted, the needle sent by minispares just wasnt right. i had to change it aswell. my nearest rr that deal with minis is about 180 miles away...lol

ok mate thought the answer would be to have it set up on rolling road!

AAA or AAM should suit your set up I would of thought. What carb is it on these? Its been a while

I dont know how many mini specialists there are in Leicester but I always used Jonspeed in Nuneaton, Warwickshire. Always seemed quite happy to give advise over the phone. Number is on the website here http://www.jonspeedracing.co.uk/

I tried an AAA needle but was way to rich! But not tried AAM! Thanks for that I might give them a ring! Cheers sorry I'm running a HS4 carb

Hi,

The AAM is slightly richer than the AAA. I have been having some problems with the fueling on my 1981 998. I have just bought a AAU. Waiting for delivery. Will let you know how it gets on.

Good bit of kit to look at.....

If you click on your desired carb (HS4 in this case) it will give you a list of needles which you can compare. Might save you a bit of cash on the rr.

This is a direct link form sucarbs.com so its legit.
