I am flying a Lancair with an IO-360....I have tried
a number of different ways to start the plane when it is hot. Some work
better than others but sometimes I think it depends on the phase of the moon.
I would really like to hear from anyone and everyone on how they go about
a hot start.
The IO-360 is also used on the Mooney M20E/F/J models and hot starts are
always an issue, especially among the pilots that try and follow the owners'
manual's recommendation of a flooded start when the engine is hot. While
your exact setup is different than on a Mooney, the procedures may work for
you. Following is an excerpt from a post to the Mooney Mailing list from
a year or two ago. I follow the shutdown and hot start procedure every single
time and it always works. Before I was taught this many years ago, I too
was convinced that hot starts were somehow linked to the phase of the moon
or something even more erratic like female moods. With this procedure, I
am as confident about the engine starting as I am about democrats raising
taxes.
COLD START PROCEDURE
Master Switch On
Throttle, prop and mixture controls full forward
Boost pump on for 5 seconds
Mixture to idle cutoff
Throttle reduce to the approximate position for a 1000-1100 RPM idle speed
Engage starter
When engine fires, release starter key and firmly (but not rapidly) move
mixture control to full rich
After engine is running, lean mixture control out for smooth idle
HOT START PROCEDURE
Master Switch On
DON’T TOUCH THE THROTTLE, PROP OR MIXTURE CONTROLS.
The throttle should be in the 1000-1100 RPM position from the previous
shutdown, the mixture should be in the idle cutoff and the prop should be
full forward.
Engage the starter
Expect about 15-20 blades before the engine fires
When the engine fires, smoothly (not rapidly) move the mixture control to
full rich
After idling, lean the mixture for smooth operation on the ground and during
taxi
FLOODED ENGINE START PROCEDURE
Master Switch On
Throttle, prop and mixture full forward
Boost pump on 3 seconds, then off
Mixture to idle/cutoff
Throttle full open
Engage the starter
Slowly pull the throttle back towards idle as the engine is turning over
with the starter engaged
When the throttle is reduced to about ½ to ¾ towards the idle position, the
engine should fire after the throttle hits the position for the perfect fuel/air
mixture for starting.
When the engine fires, smoothly increase the mixture to full rich
Bring the throttle back to the normal idle speed (1000-1100 RPM)
After idling awhile, lean the mixture for smooth operations on the ground
and during taxi
RECOMMENDED ENGINE SHUTDOWN PROCEDURE FOR THE MOONEY M20E
Idle the engine at 1000-1100 RPM
Pull the mixture control to idle/cutoff from this idle speed
DO NOT TOUCH THE THROTTLE. Leave
it at the setting it was at for the
1000-1100 RPM idle speed used for shut down
Ignition switch to off after the engine spools down
Master Switch Off
