Hey guys I tried starting my engine today but had some issues, it isn't getting fuel for some reason even though when I do a pump test with the fuel line disconnected it pours out in a steady stream with no air bubbles. I'm using a regulated valve on the coleman green propane bottles and it definitely has ignition just when it goes to fuel ramp nothing happens, it will reach 9800 rpm but it's only running on propane and when it times out it reads "Weak Gas" on the GSU? it doesn't say anything about that in the manual so can you guys give some advise to a turbine rookie please it would be much appreciated. Regards Justin.
