champion 3500/4000 generator

We have a champion 3500/4000 watt generator that will no longer start and then run our 13.5 btu air conditioner. I have called champion help line and got 2 diferent directions on how to fix the problem. The last fellow said to get a hertz meter and call back and then they might be able to help. I turn off all breakers in the trailer except the main and the ac ones. Should I just buy a new one. It starts and runs fine and does everything except air.

    The ethynol will mess up the carb and cause it to lose power. I had used mine to run the entire camper for several years but it slowly lost power and would not do it anymore. A new $27 carb from champion fixed my problem. Does it surge any at all or do you need to use the choke to keep it running smooth?

    when and how ?
    what is the situation
    are you waiting until its 100* before starting
    when Hot, do you let the FAN run 10 minutes before switching to 'cold' mode and starting the compressor,
    how old, how many hours, how easily does the A/C start on shore power ( does it need a soft start add-on ?
    did you remove the 'spark arrestor' from the exhaust and clean it ?
    old fuel or new fuel ?
    clean/replace sparkplug ?

    Will your AC run on 30Amp shore power? Get out your volt meter and measure output unloaded it should be somewhere around 125volts or slightly greater.
