Recently I purchased a used Simjet Turbine and I am trying to get it running. I get one of two outcomes. First it spooled up many times and never started on the powermax fuel, I then got a message on the data unit that stated Timed out. Next few trys it did start on the powermax but never started on the Kero. It then stopped an another message stated weak gas? Does anyone know what might be my problem? I'm new to Simjet turbines. I have run Jetcats and Wren turbines.
