Here's an example of a POH that no one I knew followed as it was indeed a bit bonkers. I mean, would you pull through 4 blades with the throttle fully open, mixture full rich and no one inside, praying the mags really
were off and there isnt a fault?
It resulted in a replacement of that section of the pups POH
On my Pup, "rosie" which doesnt have a primer (or a key starter, Hatz
), I seem reliably to be able to start her every time on first/second press of the starter button, in all conditions*. I start on the left Mag.
Im pretty cautious of over priming, so I dont over prime on the throttle prior to start, two or three primes and I dont sit there with the fuel pump running for ages faffing about. I do pump the throttle on turning the engine.
I have some sympathy with Matthew as I have flown his aircraft "Bob" and had difficulty starting him when cold. Ive not seen the fuel running out but what I do is if he doesnt start after a few attempts, well I usually give it a break and have a cuppa and come back after 10/15 min and he starts.
Im pretty sure that its low temperatures that cause the fuel not to vaporise and thus make it more difficult to start a Lycoming in the winter.*Mostly...!
