I have flown it 6~7 times now, and still find starting the engine of
new Cessna 172S quite tricky, and often I have to try two or three
times to start it. I never had problem in older C172s.

So what's the trick, guys? How much throttle (1/8, 1/4 or 1/2 inch) do
you open? How fast do you advance the mixture when the engine starts to
fire? Anthing else?

Thanks


I rent from a Cessna dealer FBO at VNY. The procedure there is:

Throttle - open 1/4 inch
Mixture - Idle Cutoff
Propeller area - Clear
Master Switch - ON
Beacon - ON
Aux Fuel Pump - ON
Mixture - Advance full - 2 to 3 seconds, then return to Idle Cutoff
Aux Fuel Pump - OFF
Ignition - START
Mixture - Advance full, when engine fires

Works every time for me.

BTW... same procedure when the engine is hot - EXCEPT - Mixture -
advance full - 1 second, then return to Idle Cutoff.
