Pulsar review: HD6580B back up generator

Purchased this generator about 2 years ago for power outages followed instructions for set up and storage. When a outage finally came along set up generator and ran it for 8 hours. Shut it down to refuel and I could not pull start the generator again ran diagnostics for raw fuel in cylinder and reset the rocker arm gap this was not the problem. The pressure release on the camshaft broke and now I will have to buy a new camshaft and tear down the generator and engine. I sat in the dark the rest of the outage. I was a mechanic for 30 years I know how to take care of equipment I got 8 hours out of this generator now do I fix it ore get a different brand of generator. I believe this generator will break again. Pulsars new name is the prince of darkness generator.
