I’ve owned a Continental fuel injected engine and now a Lycoming clone with FI. Why is the starting sequence different? On a Continental you use full rich mixture, boost pump on, and increase throttle to full open to prime, then return to normal throttle setting and start. With a Lycoming you set mixture to cutoff, throttle a little open, boost pump on, and prime by pushing mixture to full rich, then pulling back to cutoff. Crank and push mixture in as it starts. Why are the two routines so different and what makes one right for one and not the other?
