Yes I know. I recall doing a compression check. It was nutso!
I practice windmill starts Good thing. I figured on a relight after crossing a ridge if I didn't find lift. Crossed over, unfeathered prop, hit the starter button. Nothing. There was a small field right below. I would have survived. I pitched over for a windmill start. It takes a long time when you are headed straight down to get from 45 to 70. Successful. It turned out that the lead from the starter button spade connector had worn from vibration and came free on the starter. I fixed that. There is a reason spade connectors are not used on real airplanes M On Wed, Feb 8, 2023, 4:36 PM Kristin Nowell <[email protected]> wrote: > I have never had a failure to start !
