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 =BD to =BE 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
