Hi all, Been in the Wilderness the past 12 years or so and finally getting back into the MIni. I have to pull out the SU as there is no fuel getting into the cylinders, assumption is that it may be the tube from the fuel bowl to the jet. While the Carby is off, is there any expertise in regards to sizing of the needle and jet? The engine is a 1330 with an RE13 cam. Thanks in advance Gilly |

I'm running an RB needle in my HS6, Minisport heated manifold and maniflow extractors. It's 1387cc, 10.4:1 and 266ss cam. Good compromise on performance and fuel consumption. Richness set with Doc's exhaust analyser. |

OA6 and OA7 were the go to needle for six cylinder holdens The OA7 is leaner throughout the rev range . OA6 worked for me and was dynoed at a local tafe People that wanted richer went RH or SB The original 1800 TW needle worked good also . The ramp off idle is the critical bit . Download winsu and use the compare needles function |
