SOURCE: rpm surge with intermediate power load

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.

SOURCE: Yamaha yg4000d generator Surges in the economy mode!

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.

SOURCE: How many Watts will 1350 btu RV roof model use? I have a Dometic 641815 model . I want to buy this Yamaha 2400 watt generator.

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

Capabilities of the Robin 2400is generator


no
ac units are 2000 watts minimum, washing machines are 1500 watts minimum, microwave is what is on the plate and start at 650 watts but most are 2000 watts
the 2400 is the peak out put for start up of fridge , washer etc and the running wattage will be 2000 watts or less ( duty cycle )
to run more than one of the nominated items at once you will be needing a 5500 to-6500 watts unit
they handle a start up surge of 6500 watts ( larger one) and will comfortably handle 5500 watts run full load
it works like this , the plate on the gen set is the surge short time load capacity of the genset and not the duty load which is 500 to 750 watts less than that plate wattage
for example your 2400 is is surge rated at 2400 watts but duty load is less than the 2000 watts
many people make the mistake of buying a gen set that looks big enough but do not calculate the maximum load capable on being put on the gen set
fully loaded uses more fuel /hr
wears out faster
has power surges as the extra load cuts in and the motor struggles to get back to required rpms for voltage and cycles
will not cover extras like lights ,
a much large gen set will take it all in it's stride , no power surges, better economy, less stress
talk with an electrician , do your maths on everything you wish to run and that which you forgot about then add 1000 watts to the duty cycle and that will be close to the gen set you require

If may be a partly blocked main jet ( Check by slowly closing the choke), if it the hunting clears out as you slowly close it it prob blocked main or pilot jet...
If the unit hunts (flutter)at 1/4 through 3/4 load, the governor damper spring on the throttle shaft under the stepper motor needs one more turn.. only after you've checker the carby..Only one turn or you will damage the stepper motor....one a few of these....
