At Sibwings forum you will find a simplified checklist for start up.
From your given procedure I wonder why you want to lean your mixture? I read that it was very rarely used. The blue handle should be in aft position.
Also, do you remember to open oil cooler, switch is next to cowler gills. The gauge should read "Otvorene" (or something like that in Russian).
Oil tends to heat up while idling so plan your flight so that you get airborne without delay.
Edit: Sorry to repeat, a colleague was faster to answer.
