I've often found if the Ms are too lean, AH2 works fine.
Stick em into mintylamb site and have a look.

Hey everyone, Just after some advice on which way to go with needles in my mini. Currently running GY and they were a bit lean mid range, have some borrowed Ms in there now and slightly better but still lean mid range (1800 - 2800rpm). It is fine just off of idle and from 3,000ish rpm up in both cases. I have narrowed it down to DU, L or EQ with I think the EQ leading the charge for the next try <- open to suggestions on what to try next, even if it isn't on my list of possibilities. Engine spec: 998+0.020" ported 12G295 with biggest valves that'll fit ported inlet manifold Maniflow LCB Twin HS2s with K&Ns Thanks. |

depends on the position of the dashpot pistons - is it lean under load or gentle acceleration or??? http://www.morrismini.com/SUNeedlesV2.a ... &size=.090 |

Hey Simon, it's lean under both gentle acceleration and under hard accel. It is more noticeable under hard accel. |

Thanks for the help guys. The clutch in the brides car is haddit so I spent some time today getting the mini in top shape and whipped the needles out and spent some time with some sandpaper and the drill around stations 4-7 with blending 3 to 4 and 7 to 8. Must say it worked out superbly as I picked a few dimensions from a couple of the other needles people suggested and worked towards a blend of GY and an average of the others to get something that feels perfect everywhere and idles beautifully. |
