I’ve seen many people wonder if they can skip the pre-filter on their generator when they’re in a pinch. This matters because the pre-filter catches large debris before it reaches the main filter, and skipping it can damage your engine.

Most people force the cover down, but the real trick is knowing the filter needs to … Read more
I once thought a clogged air filter would just make my generator run rough. But I learned it can actually trigger a no-start condition with specific error codes. Many generator control modules monitor air intake pressure and flow. A severely restricted filter tricks the computer into thinking there’s a major sensor failure, not just a … Read more
