Thanks for your info but what I am concerned about is the additional hassles of setting one up. DH I hope you really didn't intend this to be directed at me. " For a new modeler with little or no woodworking skills yet- I can see where it may look intimidating."

My concern has to do with the potential need to move the firewall or fuel proof the inside of the fuse, create a hatch where there is none, or making a large vent in the fuselage etc. As an example, here is a picture of my edge, and as you can see the carb on a ZDZ would end up half way in and half way out of firewall making adjustments difficult at best. On top of that I would need to make a hatch where there is none to get to the needles even if the firewall was not in the way. How about venting of the fuselage. I assume that you will need a vent at least twice the size as the carburetors venturi. I'm really just asking questions about what some of the potential problems might and what you have done to address them.
