Well, I repaired mine last weekend. With the garage door closed and the lights out, I discovered that it did have spark. Being around since the old muscle car days with carbureted engines, I know that when a non-computer engine won't start, it comes down to fuel or fire; it had fire so it had to be fuel. After totally disassembling the generator, I discovered a 'tube type' fuel filter at the bottom of the fuel tank and it was totally clogged. It is not visible without disassembly. With it cleaned out, the generator runs great and starts with 2 - 3 pulls. I also disassembled the other one and found that tube filter also partially clogged. If you have one of these gen sets, I would advise that you check out that filter. Now, I have 2 good generators.
