Just my 2cents.
I have a ZDZ 80 and I find that rear carb a pain in the --. Also for the DA 50. You have to carve a hole in the mount to get it in. Then you have a hard time getting the throttle linkage and choke linkage to work - you have to carve a access thru the mount box to get at it. Also that DA 50 looks fragile to me. Great for weight but not so good in case of a mishap. I like the G45 converted to EI by Cunningham. Everything is out in front where you can get at it and the electronics is in the mount where you don't have to bother with it.
