Posted by Checking the gauges before the first start – found that the wiring of the differential fuel pressure sensor was not correct. (Midwest colour coding of wires does not match the sensor as I had assumed!)
Purged the fuel system from a 5-litre fuel can to clear any debris through the system. There was a bit well worth doing.
Followed Rotax oil purge instructions.
Started well on the second turn of the keys. Would probably have started the first time if I had kept the starter engaged a second longer. All gauges in the green. I made several runs.
First run – 2 min stop check for leaks none found.
Second run 20 seconds check turbo oil flow OK
Third run 4 min oil up to > 50 C – all good no leaks
