I think I have bad esu ,just connect brand new engine to mine brand new super Scorpion the k180g ,primed the pump both ways the pump and the burner when go for start ,the kero plug go and nothing the pump not pumping the fuel for initial start fire ,I did try multiple times and nothing I have no start ,this is not the only turbine I have ,mine k140g works perfect ,I think the k180g have bad esu or pump at slower rpm will prime both ways the pump prime and burner prime just not working when I go for start.
