The Carby is intermittently starving for fuel and is leaking from the plunger. It is a 1996 SJ70, what could some of the issues be? We only had it rebuilt 2 years ago, it's stock. |

The plunger leak is only minute. The starving for fuel happens sometimes when you put your foot down. |

You had the carby rebuilt? or the engine. If its leaking, Best off not to muck around, buy a carby kit, like $55 from repco. Put that in, clean everything while you are there, and make sure the float height is correct. Carby kit will include a new plunger. |

Re the starving for fuel, there's a stainless steel filter mesh inside the carby where the fuel line slips onto it. Try pulling that out and checking it for blockages. I had a heap of junk in mine at one point (not long after a rebuild) that meant it would starve under load but would idle quite happily. Also consider putting an extra fuel filter between the fuel pump and the carby to provide a bit of extra protection against muck in the fuel lines. |

How old is the fuel pump? |

Just took it into the Carby shop and discovered the problem is electrical.....back to drawing board. Intermittent surging. The revs cut out. |

What about the leaking plunger? Which I assume is the accelerator pump. |

You can see residue around the plunger at the front right of the Carby but it wasn't leaking when tested and you can't see moisture there so I don't know what's happening have booked it in to get analysed next week. |
