Final update. We brought our generator home, and I guess we'll pay out of pocket to get it fixed. First, they put it on a load tester, and they argued that see, it works fine! But then my husband pointed out that the guy didn't know how to convert between watts and amps, and the equipment actually showed that our generator is producing HALF the power that it should be producing. Then he told us that even though they've had our generator for two months and returned it to us still not working, we'd be back at the end of the line, so they couldn't even estimate how long it might take them to even LOOK at our generator again.
At this point, I'm convinced that they actually broke our generator.
FACT: When we took it in, it was leaking/burning oil, but it was WORKING. We took it in because we were concerned that it had a problem and would get worse.
FACT: It hasn't worked properly since they changed the spark plug and we got it back.
FACT: They sent it home as "repaired" because they don't even know how to use their own equipment.
At best, they're incompetent. read more
