[Chook]

ICCARS - I'm not sure if the states have different legislation or standards/levels but I do know of a couple engineers who support carbs in NSW. And really it's not the engineers who test this, it's the RMS who test it, and then the engineers confirm it back to them that it meets their specifics. For JD - I'd suggest to call a few different car clubs to see if they know of cars that have been built/re-built with carbs and then ask who they used as an engineer. Alternatively get a hold of who's on the panel of engineers and go down the list. Either way you should find out if the state has tolerance for them by doing one of those.
Best of luck!!!
