Wow, you got enclosed instructions! I only got a receipt with mine. Can you post a copy of your instructions, or at least info about the adapter?
I haven't been able to figure out how to mount a cleaner; the exposed throat is short as well as narrower than the standard Zeniths. My one gripe about this carb is that it's a lot noisier than the original Z1. I would like to mount a filter not so much for cleaner but for noise reduction. I've seen a different model carb sold with an adapter. My concern with the adapters I've seen pictured is that they narrow an already-small air intake throat.
Other surprises that might await you are that it's a bit harder to start; since there's no enrichment I find I have to hold the choke partly closed for a few moments to keep a cold motor running. Also, you've probably noticed that the original gas line connection doesn't work; I went with a rubber line. I've set the T-valve to 1/2 turn open; any further open and there was obnoxious surging and noise.
I love its resistance to vapor lock and sudden-stop stalling.
