The problem is the governor and is easily fixed. Do the following: Remove back and side panels to expose fuel tank. Insert screwdriver into fuel on/off switch on front panel and remove. Now remove top panel. To do this unscrew fuel cap, pull out fuel spill surround rubber and remove top panel, just pull gently. Now with fuel tank exposed, remove retaining bolts. Gently lift tank and rest on frame. No need to disconnect fuel line.On top of carby is the governor, protected in a black plastic shield. Unscrew the retaining screws that hold it to the carby. Remove electrical connection and then remove governor from carby. Now remove cover by pressing on the three retaining plastic clips and prize upwards. Now the solenoid is exposed. Remove solenoid from its base by unscrewing the two retaining screws. Now that the solenoid is fully exposed use an spray on electrical cleaner that can be used on circuit boards. Spray the base of the solenoid in particular the spindle. Whilst spraying the spindle rotate it a few times until it moves freely. Then replace everthing in reverse order. Where the spindle exits the solenoid dust particles collect and increase the friction between the two surfaces. If you do not want to proceed as outlined tell your dealer it is the solenoid and have it fixed under warranty.

Economy mode is not really meant for use when you are working, more like when you are idling and using only a very small load, it must be run in Normal mode when driving the Normal load. As the Engines Rev's are "Tied" to the "Draw" from the "Outlet". More draw, the higher the rev's need to be, but in economy mode,it is Governed, and cannot Rev up enough to supply full power.

Hello, I have the same exact generator, 2400 Yamaha. It works fine for my Ac, and then some. After it first kicks on, is the biggest surge. Then I have even after ac is running, I have had tv on and even used microwave. But as far as running you ac on your rv , not problem. I do it all the time. Mine is ulta quite, and 8 to ten hours run time on about a gallon of fuel. Mike
