1974 Leyland Mini 998cc 1 1/2" SU Carbie Currently has a BQ needle and is running Rich. Black smoke, doesn't idle, sometimes doesn't even run all the cylinders. When you floor it is almost konks out. Aparnetly it ran fine on a 1100cc I have got extracters and an aftermarket inlet manifold. And on a side note, the sexiest dual exhaust ever heard. What needle do I need? Please help. |

Theres a program you can download, called WINSU. It has a feature where you put in your engines details, and it tells you what needle. You can only use this ferature a couple of times unless you pay for it. |

I am running a stock 998 with HIF38 (1 1/2"), RAMFLO filter and an ADS needle. Car never misses a beat and runs excellent! Standard for an HS4 is ADF I believe. |

Lets assume I have tried alot of other things to get it to work before resorting to the needle. I tried running WINSU, but it gives me a .net framework error. So I installed the framework it links me to. Restarted, Still doens't work. I have taken my Carbie into my local mini shop and each time I got in, a different person gives me a different answer. Which has been costly so far. Please, cant someone save the day with their massive........... intelect? |

OK for starters, if it has a BQ needle now it is a fixed needle carb... the floating needle that JAM_IT listed won't fit. Only book I have handy that lists any needles for HS4 carb is the Leyland black workshop manual. It has a listing for a 998 automatic with HS4 (1-1/2") carb- Std needle AC Rich needle M1 Lean needle H6, Blue spring in dashpot. Hope this helps.. 
Buying needles is a lottery, there are hundreds of `em. Try this program- http://www.teglerizer.com/suneedledb/index.html and, this- http://www.mintylamb.co.uk/suneedle/ I'd find someone with a dyno and an A/F meter, that tunes SUs- do it properly...
They should only charge you for the needle they use, not for a bunch of them. As TheMiniMan said it could well be another problem, flooding, air leak, etc. |
