Can't think of any at the moment. I have a feeling you're gonna have to go 100% custom and build it yourself. I bet a home-improvement store would have a PVC elbow with the correct I.D. for you to build from. I just can't think how you'd secure it to the carb. I'd be interested in seeing this when you're done with it.
