Query: Ran good twice, now no support. Poor power quality.

Bought this at Walmart for $300. It started easily the first 2 months. A year later the carb is leaking gas when I open the fuel shutoff valve. I work on cars all the time and checked the usual items. It is the carb, not the hoses or clamps. I went on the Devilbiss website and it is not listed as a current model. They have nothing like it now. I'll buy a Honda next time. Update - still have it 2 yrs later, runs after lots of carb cleaner (run it dry, don't trust STABIL alone)...I now have problems with poor power quality, voltage swings, poor grounding even with ground rod, and no voltage to safety ground, only 105 volts from hot to neutral. I think it fried my refrigerator computer board - I won't use the generator anymore for anything electronic or valuable.
