As an update to my 2000I, having seen the professors video, I decided to look into mine a little more and sort out the burping, and uneven engine speed. When checking it out more closely, rather than just using it, it became quite obvious that it's running quite rich, which is somewhat normal given the lowest I ever operate the unit at altitude wise is about 4200 feet.
I contacted customer service, and they responded right away recommending a hotter plug. When I changed it out, I found the factory plug was quite fouled with black soot, more than I expected even though I knew it was running rich. The new plug helped, but I still find the unit doesn't really do what I'd hoped for when I bought it.
Biggest issue I have is that the little champion just doesn't like my WFCO 55 amp converter in my TT. The power factor on the converter is .67, which is murder on the generator. If I let my two type 24 batteries drop down to about half charge, the converter draws right around 700 watts when I first plug the trailer in to the generator. With that much of a reactive load the overload trips right around 700 to 720 watts, so half the time when I first plug the trailer in, it kicks the overload. Trying other less reactive loads I can get up to 1600 watts, sometimes slightly higher. The other issue with the converter in the TT is that the generator tends hunt a fair bit throttle wise when trying to power the TT with nothing else on, which is something it doesn't do nearly so much with other loads. On an intersting side note, I borrowed a little 2 cycle 1000 watt generator which is only rated for 800 continuous and it works great with the power convertor in the TT.
Bottom line, the spark plug helped a little for the altitude, and will probably work until they get an approved altitude kit for the carb, so I'm pleased with customer service. That said: For using the 2000i to charge the batteries in the TT, and run small stuff like the microwave etc. I find the 2000i is not really quite up to the task.
