Vapour lock? problems with new installation Rotax 912 ULS
Anyone got any advice on how to deal with what appears to be recurrent vapour lock problems?
We have checked that fuel pipes route OK. Have put in 30% avgas (100LL) to reduce problem and have a vapour return that is working. Symptom is that when you apply full power after a bit of taxying (so the small space under the cowls is pretty hot), coolant at 105 degrees C, at about 5000 rpm there is a sudden loss of power.
We thought we had done everything we needed to get rid of this problem but it persists. Could it be anything else?
Help required....
