Difficult engine starts

[Warhound]

Throttle at 25% sounds way too high to me..I use somewhere between 6-13% with a cold engine and it starts every time. Once the engine is at operating temps it will start at higher throttle seting too, which is probably why it works fine with temp effects off.

Is easy - CEM and ETE on - only need:

Fuel cock on
Throttle ~10%
Igniton
Radiator open

Advance throttle slow (5 in 5%) until engine warmup.

Fly

Some "click, click" procedure in YT videos worth only for good show in movies.
