The demand fuel injection system has served us well.
As a wise pilot once said to me, imagine starting your car, warming up, running just under redline for 3 minutes, then 5,000 rpm (80%) power for 10 minutes. Then drive at 65% power (around 140 km/h) for 3 hours and then coast home.
Imagine doing that 6 days a week and you gain more respect for the long stroke air cooled aircraft engine, designed long before computers. He was, as always, quite correct.
