I know that hot starting IO-540s is a subject for considerable debate. I
was taught a method that I was told worked 100% of the time[1], and up
until yesterday it had. But yesterday, after flying for an hour and then
sitting in the hot sun for half an hour waiting for customs, I couldn't
restart the Lance and had to have it towed back to the tie down area.

So what would you do in that situation?

Good question. I've had one of the beasts for a month now, and it's a crap
shoot every time.


[1] Leave the throttle, mixture and prop alone from when you shut down.
Turn on the fuel pump, and crank. When it catches, quickly advance the
mixture to full, and once it stops spluttering lean it out.


Haven't tried that, yet. How long do you leave the pump on?



Here's another method from one of the Cessna Pilots Ass'n forums:

Hot start:

Throttle in 1/4" from idle.
Mixture cutoff
Fuel pump on
Mixture full forward until fuel flow just registers (about a long
one-one-thousand)
Mixture cutoff
Fuel pump off
Crank - after about six to ten blades (3-blade prop) it will fire -
immediately come foreward to full rich.

Shorten or lengthen the priming time from one to three seconds depending on
time since shut-down.
