Hello,
In fall of 2019 purchased a new Jetcat P130-RX from Dreamworks, and installed it in a scratch built Ziroli Turbinator. Test running the installed turbine resulted in successful starts under half of the time. When it won't start, the GSU reads low temp and fuel drips out the nozzle. So then install a rag and tilt the Turbinator on it's nose. Lots of fuel then pours out the front of the engine onto the rag. The engine then usually starts the next attempt, but not always. When can get it started, the P130 appears to run just fine. But getting it started is like a trip to the dentist. So put the project away for the winter. Am now getting ready to run the Jetcat 130 again. So what am I doing wrong?? Any advice?? Help would be much appreciated. A few details are........

100 ounce Dubro fuel tank with BVM hopper tank
LIFE XS power 2100 mah 3S 9.9V ECU battery
Jetcat oil mixed with JET A fuel
Two 4200 mah nimh batteries into an expensive S-bus Futaba RX
Running engine with two channels into receiver
Fuel filter near engine and am using a fuel shutoff valve

Many thanks in advance,
Alex
