Does anyone have a schetch of how a bow vent is piped with a clean out for Massachusetts

Welcome CLD, there's a top flight plumber here from your area. Hang tight and I'm sure he'll be along.

Is this for an island?

Is this something like what you want?

Hi guys...

Here are a couple island sink vents from the Massachusetts area. Install full-size cleanouts on the drain and the vent under the sink and you can use a long sweep elbow in place of the wye with cleanout. Mass. Also has a drawing of another way to pipe these up, but it is for multi. Floor/multi. Island sink installations.

Questions... let me know, OK?
