Hi Markoz, I feared to get no answer about this very, very old problem - therefore many, many thanks about.  :D
Hm - the "simple way" doesn't work. How I wrote in the first post - the engines sound like trying to start and stop - like an endless loop sound.
The fuel feed switches are aligned - nevertheless: the endless loop sound.... .
Your Legendary F-104 - unfortunately made only for fs09  :'( - is easier to start.... .
(I'm just analyzing the start video with the BUFF  - phew......)
