I would say too lean on the carbs. Should be a slight tan color. |

As George says and/or timing out? Steve |

I have found that with the current unleaded fuel in Australia that spark plug and exhaust pipe colour are unreliable indicators of fuel mixture. I always use a wide band Lambda sensor to analyse the exhaust gas. MIck |

Phil, Definitely too weak, plus our cars need to run richer on today's ethanol fuels too, to avoid overheating. Regards Colin |

Hi - thanks for the comments. What effect could the timing have on the spark plug colour? If it was too far advanced could this be the cause? Phil |

Burning too lean. Could burn a valve or worse. Needs to be a light tan or brownish color. Black is too rich = sooty deposits Cheers Gary 79 MGB |
