Ellison TBI
Steve- Here are my 2 cents, the TBI is physically smaller, lighter and much more simple than a typical carb. It creates a fog of fuel across the throat of the intake through the fuel metering tube giving much more even fuel distribution to the cylinders.The intake diameter is adjusted with a sliding block, changing intake flow based on throttle position/fuel flow. And because of that it is possible to lean more aggressively than a carb. Initial adjustment is not very complicated but I did have to make another adjustment on either the mixture or idle (can't remember which) within the first 10 hrs but have not had any squawks since. You would need a primer for starting....that's a minor item. Also it can be mounted in any orientation and is unaffected by aerobatics.
That's all I can think of for now...let me know if I can help with more info.
CAVU,
