After a lot of deliberation on aircraft type, I've decided that a Citabria would satisfy my mission of flying around, causing mischief, goofing off, and occasionally taking the wife to dinner.
I'm wondering if a IO-320 powered 7KCAB is worth looking at as a 'fun and economical' first airplane?
The reason I pose the question of injection vs. carburetion is that I understand carburetors. I've messed with them.
I have a long history as an automotive machinist, engine builder and drag racer so the concept of lean or rich of peak is understood. I don't want to start that lean vs rich of peak thing but I do want to know how a IO-320 compares to a O-320 in efficiency, power, smoothness and trouble free operation?
I can see where the injected engine may have better cylinder to cylinder fuel distribution and subsequently, EGT temps will be closer together, 'but' does this advantage equate to a better fuel burn number than a 'properly leaned' carbureted engine. With the Citabria 7 series of aircraft having both IO-320 and O-320 engines, this may be a good aircraft to base this discussion on.
The only problem I can think of with fuel injection is that auto gas is not STC'd for use in it. Also I have no concept of how the injection system works on that engine. I'm leary of things until I know what makes them tick.
Maybe I should just look for a 7ECA project with a 0-235 and enjoy (and learn from) flying with less power.
Any projects out there?
