Just be aware that there are more than one type of weber within the 45DCOE range now and that the more modern ones use a different float height than the earlier ones, so make sure you are comparing apples with apples in that regard. The specs above should be a good starting point though. |

Many thanks to GTO Green Have finally fitted 45DCOE 152 Weber and running fine with 36 choke, 180 air corrector, F20 emulsion tubes, 40 pump jet, 50F9 idle jets, 4.5 Aux vent and float height 14mm(drooping!) Copied half internet downloading tuning info ... Using gooseneck manifold with 16mm ram tubes and wire mesh filters . Just clears body without modifying Significant increase in power over the SUs |

All setups are different. You would be amazed at the benefits of getting it set up properly on a rolling road with a tuning expert. Sometimes smaller chokes work better for instance. If in Victoria contact http://www.racepointdevelopments.com/ Len Read is an expert on setting these up. HRS |

Hey miniscule. Go see platinum automotive in cockburn central. They have done quite a few local perth minis.then jump into perthminidrivers on Facebook. Most of us perthies on ausmini are there too. |
