Today I wanted to fire up the DuroMax XP4850EH dual-fuel generator I bought in September. I ran it on propane after I bought it, and it started immediately on that try. My intention has been to mainly rely on propane, so I left the host and regulator connected to it and coiled up.
When I pulled it out of storage today and connected a full propane tank, it would turn over but not start. Much cussing ensued.
I tried another battery, in case the one that came with it had drained too much to start the engine. No dice.
I pulled the spark plug. It had a very little bit of dirt on it. I replaced the spark plug (setting the gap first). No dice.
I then decided to try it with gasoline. I used a battery-powered transfer pump to put some gas from a jerrycan into the tank.
And guess what, it started right up. I ran it for about 10 minutes. I then turned it off and used the pump to put most of the gas back in the jerrycan. Then I started it again and ran it dry, which took about an hour.
My theory is that there's something wrong with the propane regulator. It might be clogged. I'm going to see if I can blow it out, or get a replacement. I should have covered the regulator with a plastic bag and sealed it, but failed to do so. Learn from my mistake.
I'm just glad that I discovered this before I needed it.
