Thanks for explaining this Robert but you didn't answer why the Hondas are so hard to start when they are cold. Mine is a bear too when it is cold.
As you probably know, carburetor engines are very picky about air/fuel ratios and ambient temperatures. When the engine is cold, the engine requires much more fuel than air, thus a choke is necessary to create the proper ratio. Due to emissions rules, the engine is already very lean, so is can be a challenge under such conditions, and the fuel system on the EU2000i must be able to function flawlessly. Any obstruction or restriction can reduce the fuel flow and make a cold engine difficult to start.
Once started, however, a warm engine can operate with a reduced air/fuel ratio, and a tiny obstruction has less effect on starting.
Unless there is a mechanical issue with the choke plate not fully closing, difficulty in starting a cold EU2000i is likely due to a fuel delivery issue, likely caused by some tiny obstruction in the carburetor. This can be avoided by NOT storing fuel in the generator for more than 30 days; always drain fuel from the generator if will not be run in 30 days or more. Never use fuel in the generator if the fuel is older than 30 days old. Never use fuel with more than 10% ethanol. 86 octane fuel is all that is necessary.
Stale or decayed fuel it the absolute #1 problem / issue with poor running / starting / performance in small gas engines.
Finally, most generators use a gravity type system that lets fuel drain from a fuel tank to the carburetor. On the Honda EU2000i, the carburetor sits a bit higher than the bottom of the fuel tank. So, the EU2000i has a small vacuum-driven fuel pump that drives fuel from the bottom of the tank to the carburetor. Allow to sit for a while, the fuel system can lose its prime, and it may take a few pulls to pressurize the lines and get fuel flowing again. This is why it takes 5-10 pulls to start a new EU2000i or one that has been sitting a while.
