i guess you mean weber sidedraughts why not buy a guage and tune them yourself ? its not that tricky, and its probably easier than trying to find someone who knows how to do it properly..hell most people hevent even heard of tuning them by ear anymore ! Also do you know if the venturis, jets and emulsifyer tubes etc are all right for the job ? if not i have a program that works out what you need depending on the powerband you want the car to run in, email me at raskas@iinet.net.auif you want it
