Not aircraft or engine specific but..
In Canada we used to burn Jet-B.
With the demise of Jet-B we were obliged to use Jet-A or A1.
It became normal, on occasion, to have a flameout on the first start of the day on a "Cold Soaked" helicopter which had not been preheated.
Wait a minute or two and restart...no problems for the rest of the day.
I miss Jet-B.
