914 ul can only idle
in General Tech Discussion
8 years ago
I have a Rotax 914 UL installed in a Sling 4.
After 4 hours of perfect performance during flight testing the engine now won't rev past 2500 rpm.
It is starting easy, idle and rev to 2000rpm without problem, but going faster the engine will stop.
I suspected fuel starvation but the fuel pressure and flow from pump seem to be OK, EGT's are same for all cylinders.
Any advice?
