That is normal. Only EFI engines will not require added throttle when cold
(usually).

Hi,
Just bought a brand-new Merc 9.9 4-stroke. When cold, it won't start at
idle: I have to push the "high idle" button and give it some throttle. Is
this normal, or should a brand-new engine start at idle, even when cold?
