Not sure if the rich afr rules this out but I had a lumpy idle on mine, the cause was an air leak in the end. Have you tried brake cleaner on similar on all the joins? http://www.turbominis.co.uk/forums/index.p...tid=469104&fr=0 |

What sort of RPM is it ticking over at?

The vans map is/was quite aggressive at low rpm. this caused Craig some running problems at low revs On 11th Feb, 2015 robert said:

it's a balancing act mate.

i believe the standard static timing of a metro turbo was 7 degrees @ 1500rpm with a distributor.

the one that came with your carb. at least it runs and no smoke. think il be buying a bdd and start from the begining. the needle thats in has been profiled and the mixture screw was all the way in before i adjust to get it to start. Done now needs redoing lol |

I've emailed you some maps to get you started, try the 22 degree one. It should be pretty safe. Also it would be a good idea to get a BDD in there as a starting point. If something is worth doing, it's worth doing half of. |

Check the cold start mechanism on the carb is not leaking internally, not uncommon.

Set idle advance at 15 degrees and then tune idle air and AFR to ~14.7 to get to your idle rpm. now adjust the cold start linkage as per the book i shall look into this Done now needs redoing lol |

The fault here is not the vans map, on idle you must find the the fault.
