Post subject: | Mini Problem: Pre-Ignition? |
Hey guys, having a little problem with my mini. Sometimes when I turn it off, the engine just keeps on going. Sometimes this happens for a short time and stops and other times it goes on for a long time before stopping. My dad told me it might be called pre-iginition. We have changed the spark plugs as we thought this may have been the cause (and they needed a change). Any help on fixing this? Another thing, I think I may have a bit too much oil in my engine. Is this a big problem at all? What is a good mini oil engine pressure? |

You may have to lift the head and give it a de-coke. If its a bit oily and you only do short runs it will coke up a bit - you may get away with a coupl of good long steady highway runs to burn it out |

we all quickly learn how to pop the clutch at the critical moment. ![]() ![]() |

I had this issue in my old 1100... Turns out it was a combination of two things. 1) Timing too far advanced 2) After long runs the lobes in the chamber of the head would heat up and act as a glow plug and given the excessive amount of carburettion I was running and the richness of the mixture it would keep on running.... This was my first Mini and I had no idea about tuning cars ![]() So check the timing, if it's ok, learn how to pop that clutch or how to take the head off and die grind the lobes ![]() |

'Run on' is often caused by a too rich or too lean carby. ![]() I have the same problem too sometimes - usually a warning that my oil is getting low. ![]() |
