I have a Spit Mk3 with a tuned engine. The car is used for road use. At the moment it's fitted with twin HS4s & AAA needles while on a road test with
C/O meter fitted it's running rich at low revs and lean at high revs speed. It starts to get lean at about 4000 rpm. I have the WinSU needle coparison
program and have selected 3 needles ADX ABY and AAM. Can any one help me narrow it down or suggest a different needle. Thanks.

You may need to elaborate on your setup... the engine mods and the exhaust...
If only for my personal interest :o)

69 Signal Red Spit (with planned mods of HS4s :o) )

james is right, need more info, AAL or AAM ar probably the ones to be looking at though! ABY will be to rich unless you have a radical setup (i
have a set of AAL's and ABY's available for a small sum)

I would advise you to get to a rolling road, make sure they have a good selection of needles available. Then in about an hours work all this will be a
happy memory.
