Caring for an infant is certainly not easy and very taxing on the sleep schedule, but honestly it feels less complicated than modifying and tuning a finicky small engine -- and engines don't smile back at you!
Infant cries. = check diaper
Still crying? = put food in infant
Still crying? = hold/swaddle/rock until sleeping
Repeat every 3 hours.
Anyway, little progress on GB over the past week of course. When the baby is napping, I've been doing more engine runs with different main jets, needle valve settings, and propellers. Fuel flows are being measured with a digital scale and confirmed to be good enough.
Hopefully we will make more progress in the coming weeks.
Stay tuned! (get it? get it? -- engine pun) [rimshot] "i'll be here all week!"
