Has anyone fitted 40mm venturis to his 48IDA and has some experience to tell ?
Or is everybody still choking along on 37's ?

I now have 40's and the car runs better than ever and the plugs are not sooty anymore. I really think 42's would work great. I still have a little stumble at 2400 or so after changing to F16 e tubes. I probably need to try different idle holders(ie-less than 120's.)
