Question about Power Generators
When running on auto sounds like it isnt getting enough fuel
You didn't say, so I'm assuming that this is an LP Vapor fueled Home Standby generator. The bottom line to these things is that if it sounds like a fuel problem it almost always is one.
1 - Check for leaky fuel supply plumbing.
2 - Check the fuel pressure at the input side of the demand regulator inside the generator, it needs to be something like 11 inches of water all the time. My Generac/Guardian training came with a nifty manometer just for this purpose. If you can't get a manometer your LP supplier should be able to come and make this measurement for you. If you aren't comfortable with adjusting the gas pressure you should call them anyway.
3 - Change the spark plugs. This isn't all that common a problem, but it's cheap compared to changing the demand regulator.
4 - Check/replace the demand regulator inside the generator. This part controls gas flow rate rather than gas pressure so if the diaphram in there gets sticky or leaky you can have fuel problems.
