Hi Greg;
I think you are mistakenly believing that NA means carbureted. It means
Naturally Aspirated (or normally aspirated) or in other words - not
turbocharged. Most installations are currently fuel injected and I would
guess that most of those use Tracy's EC2 injection/ignition controller.
There are a few turbo installations in progress and I think that besides
myself there are a few others flying.
There are a few carb installations flying as well. Finn? Peter?
