Generator Bundle with Lamborghini Engines - 6kw

I am selling two identical 6kw generators as a bundle. You will see from the video that one is working perfectly - it starts with the first pull and produces electricity without any issues. Also in the video, you will see that the engine on the second generator starts using the easy-start spray, but it experiences diesel flow issues. I know the tank probably needs replacing. Also, the engine is not at high enough revs to test the generator itself. It can be repaired or used as a spare. The engine is a Lombardini 15LD400 engine. They are renowned for their fuel efficiency and reliability. The generator itself is also an Italian manufacturer. I have changed the oil and filters on both engines.
