Online Community of Zenith Builders and Flyers
I thought that was a good question and emailed Arion Aircraft/Jabiru Engine Services:
The Gen 4 is a drop in replacement engine for all installations except some very early 2200s.
The Zenith 750 has specific airducts for the cowl which don’t fit the gen4. However the gen 4 airducts are easily adapted to the 750 cowl, we have several 750s flying with Gen4s.
Thank you for passing along the engine class seminar. I will have to find your group and join it.

I got my FWF kit from Pete in 2018 and my Gen 4 fit well. The only issue was the second camloc on the left side did initially rub on the airmuff. A small fiberglass patch job was all that was required. I believe I fit the cowling without the airmuffs on the cylinders...
