Now to start the troubleshooting because I didn't get this generator because it ran well! First check for fuel. I took the hard fuel line off the engine to make sure fuel was being pumped by the fuel pump. It surely pumped fuel and I ran compressed air through it as well just to make sure it was clear. Then I took the injector out of the cylinder head. It is held down by a retaining plate and two 10mm nuts. Once the plate is off you then twist the injector a few degrees counter clockwise and pull it straight up and out. Here is a video I took of the injector pumping fuel and making it mist out of the 4 holes in the top. This sucker sure does squirt a lot of diesel!!
