I don't know anybody who has made it work on a sidedraft Weber or Dellorto. There is too much pressure shock in the port.

I've not used it for 15 years (45 Dellorto) and my economy ain't bad without now it's jetted properly.

Cooper S never had it fitted anyway, nor did a long list of performance cars.

hardly any of the DCOE webers had the vac port anyways,,, only the very late pollution type things like the 53 & the 56 series had them i think ???
