Ilikeflying: In my mind there really doesn't seem to be a lot of benefit in having the throttle in by some made up amount, resulting in the engine revving up way past 1000 on a cold winter morning in the time it takes to get your hand from the mixture to the throttle.
You should have your hand on the throttle during the start not the mixture.
As the engine fires set the RPM with the throttle then set the mixture to full rich. This way there is no excessive revs as you start.
The engine will run for several seconds before you need to advance the mixture.
The method I use for a Lycoming fuel injected engine that works every time is,
Cold start :
Set full throttle and mixture
Prime till fuel flow gauge rises and stabilises
Mixture to Idle Cut Off
Set Throttle to idle
Hand on throttle and crank engine.
As engine fires up set RPM
Mixture to Full Rich
From a cold start I've never known an engine not to start first time using this method.
Hot Start
I find hot starts are not generally as easy as a cold start.
The need to prime depends on how long since shut down.
If it's only a couple of minutes I don't prime at least initially.
If in doubt don't prime for the first attempt
If priming is required prime till fuel flow gauge starts to rise.
Mixture to Idle Cut Off
Set Throttle
Start cranking while slowly advancing throttle (go to full throttle if necessary but be ready to close it back to idle as soon as the engine fires).
As engine fires set throttle
Mixture to Full Rich
Don't crank for more than 20 seconds.
If the engine doesn't start first time, and you haven't primed to start with, prime till fuel flow gauge starts to rise.
