Please don't use MG carbs to talk about carb reliability or the lack thereof. That's kinda like using Lucas to tell why electrical systems are bad.In 40+ years of driving I've never had an EFI issue. Carbs? Let me tell you about the MG Midget....
Even my Suzuki Boulevard was FI. The 2005 was a carb and the 2006 was FI. Night and day compared to each other.
I use a carb and it's the same model the O-200 uses and they are quite reliable. Admittedly they have had teething problems (as every technology has at some point) but for the most part they work very well and have done so for years on training aircraft.
I currently own a 2007 Boulevard with F.I. It's the same engine that I had on my Intruder that had dual carbs. The fuel mileage is a bit higher on the F.I. engine but the performance and starting is about the same with either.
I won't fault anyone for using F.I. and someday the carbs on planes may very well disappear as they have on autos. I have experienced (in a friends aircraft) a rough engine when the fuel injection got wonky on it. Engine ran enough to get to the airport and make a precautionary landing but the old adage is true ... if it's man-made it can and will fail at some point.
