Took a closer look at the carb and found the altitude scale goes from 0 to 6,500 feet and that should have been close enough for it to not die at 7,500 feet. I also noticed that the altitude knob doesn't stay at the 6,500 feet mark but springs back to between the 3,250 and 6,500. So that means that the altitude knob is adjusting for a richer mixture for 4,875 feet and not 6,500 feet. That's a difference of 1625 feet and another 1,000 feet higher which I was camping at totals 2.675 feet. I think that's where my problem lies. Since this generator is California compliant I will stop there,. But I believe I found the solution.
