The lack of low-end adjustment would be a problem to some. But I am using those engines on planes that handlaunch and belly land. So, I really don't need an idle below 4000 rpms anyway.
I have an older Norvel 15 BigMig (the bushing version). That has no low end adjustment. I also have a Norvel 15 AME (ball bearings version), that has twin needle carbs.
