Hi I have had my 2000is for a couple of years now. No problems at all. Started using for the first time this year with no problem. Next day while trying to run my RV microwave (as I always do) it started to overload. Now it won't run anything for long without overloading. Could it be water in the gas? Although the engine purrs like a champ!
I believe it was water in the gas. Anytime I run it in the rain it starts doing it again. Mechanic told me that they can get gas in the tank through air filter. I drain the gas and add a little Heet. Seems to do the trick.
