Doing a tune on my Zeniths ,cant find an exact rpm range and done a ton of research ;
Bruce Anderson mentioned 1800 in his book, Factory says 1000 in the gary.suggate site factory manual, Haynes manual tells us 1000. So far I have tuned throats @ idle ,1000rpm ,1400 and 1800 on hand throttle and strangely I get the same balance any way ?. Now thinking its not an issue but would appreciate feedback from 6yl guys with carbs,TIA,cheers |

Well done Dean, will be like new! Glad you found another vendor. I may need a few new parts for my Zeniths they’re boxed up currently. I need to prep for winter storage soon. Will run tank dry like you did. Maybe i should run another filter pre pump (IMG:style_emoticons/default/idea.gif) .
Keep at it mate! |

Thanks mate ,dropped carb parts off today and should be ready in a day or so then the long assembly job begins . Pleased to know this guy as he has a great rep as a tuner of Porsche 911's and has owned 2 short wheelbase cars in the past including an "S'' , he is a clever guy and real easy to talk to with a wealth of knowledge on anything with 2 wheels also. Yes Dion I think a secondary fitter has worked for me and certainly can't cause any problems besides I believe others have done this to good result . Some lessons learnt here and will change how things are done ,TBO don't want to do this again (IMG:style_emoticons/default/sad.gif) ,cheers. |
