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... |

I don't have any flat spots, but everything is tweaked to the 9's. |

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... |
