You can get 36mm venturi's from folks other than CB.
http://vwparts.aircooled.net/Dellorto-DRLA...-venturi-36.htm I did have to trim about 1mm off of them for my carbs. Apparently there are quality control issues... |

(IMG:style_emoticons/default/popcorn[1].gif) Mine is a unique case. I run the car above 7K RPM for autocross. I don't have any flat spots, but everything is tweaked to the 9's. |

Mine is a unique case. Mine too. Race only, cams/compression "warm" build by Foley. The "Dellorto Bible" is a (poorly-edited) book, filled with excellent info about these carbs. I recall it recommends 34s, along with some baseline jetting/air correction info. Get a copy of it. https://www.cbperformance.com/product-p/0101.htm Street car is all D-Jet, all the time... |
