Keeping in mind that the majority of you don't understand Swedish this is an occurence report as a result of lost vaccum pressure during climbout over a dark wooden area. A situation where you most need the horizontal gyro. Prior to start-up, the prop had been turned backwards when it opposed to fire off. The pump was quite fresh, only 170 h old.
