I seem to remember seeing a post or two referring to a shop that can blueprint your carb based on your engine specs - cam profile, timing, compression, heads etc. Does anyone know of a place that provides this service, to go through my 850 Holley on my 418? I've got an off idle stumble that I have not been able to resolve easily. I have read miles of e-mail strings on the subject and still leaves so many variables open that I may need some professional help with this.
