912 ULS poor starting

Hi. I have poor starting on cold engine..
My start procedure is:
- electric pump ON
- choke FULL
- throttle on Idle
The symptoms:
- I have to crank a long time - usually two times for 5 s...
- Engine try to start but cuts off after a 1, 2 turns, after this engine starts normally
- If I pull choke (off) 2-3s after startup it will cut off
I checked carb balance - it's ok on on all range
Lowest idle RPM are about 1750-1800 RPM
No soft start on engine.
I'm thinking about make carbs regulation from beginning - mechanical and then pneumatic... but I'm not sure if no I have balanced well.
