I agree, I think its given a useful life, but a short one indeed. I am a curious person by nature, and figured I can learn something. I am wondering if it ate a ring when it was installed. I don't plan on putting anything more into it, and I hope to replace it very soon. I am very lucky in the 5 years or so I've had it, its only ran more than exercise time once, and even that was short. I was watching a lot of videos on the OHV Briggs, and they seem to eat head gaskets, and move valve seals. I plan on doing a compression test too, it sounds like its leaking. I did consider looking for used heads but, I don't think its worth it, especially given the new code for me would be either a new panel for this gen and run limited stuff, or when I get a new one I can power the house according to code.
What does one do with a generator in this state? See if I can sell it for parts?
