I'm not quite sure if your issue may relate to most inverter and auto-load sensing generators or some gas-powered equipment.
Most power cutters/grinders such as Stihl or Husqvarna, specially the higher cc models do sound crappy without load, you'd think there's something wrong with it from day 1. This is normal. Well, some of these machines lack the load sensing capability thus does not adjust throttle variably according to load.
Modern generators, specially the inverter ones along the 1000 to 3000 watt range where the Yamaha 2400 falls into category, have a switch where you can choose to let the unit sense and adjust throttle according to load. If this is off, the unit might sound like its not running smoothly on idle. Depending on you, this can be alarming or not. On a Honda EU2000is, for example, it is noticeable when the auto-load sensing button is off but not be like its choking or sputtering.
Anyhow if it is idling roughly, I can only come up with 2 possible causes, if I may suggest:
1.) the cable that gradually pulls the throttle (to open wide or close) on the carburetor - normally called governor cable (although it has different configurations on different engine types) needs to be adjusted/tightened. Or replaced, if worn out. Before new cable, put lithium grease on cable - it helps a lot.
2.) throttle adjustment might be necessary. At most Yamaha servicing dealers, it is included when you have a carburetor tune-up. They will check the diaphragm for blockage or holes, gaskets for leaks and filters, well, the entire integrity of your carburetor. This resolves most rough idling issues.
I know it would probably save you at least $65.00 if you have to check this yourself and buy the spare parts. However, going to a servicing dealer may be the best solution but always be sure the repairs are warratied. Hope this helps.

You will need to know the BTU value of each type of fuel to compare the difference of each to one another. Nito methane is not a fuel as such, it does bring extra oxygen into the mix.

Check your air filter, and the oil level.
Make sure you're running on a flat surface.
You may also want to clean the carb and all the carb jets with spray carb cleaner, and check the gas filter screen at the tank exit.

Tom...what can I say - what you did was not very smart. Next time draw a diagram BEFORE you take the wires off!

My answer:

Hello Bill:

Here are the site links you'll need to check and/or get info, or buy your adapter kit for your Yami YG4600D Genset conversion kit.

Most likely it's running an 8 or 10HP engine on it now? In any case it's most likely less then 12HP. Not sure what size engine you have, as you didn't say only for the model #? On older Gensets it's harder to track down the HP rated engine is all.

For your Yami YG4600D Genset there you most likely will have your choice of at least 4 adapter kits depending on if you are going to keep gasoline as an option. If you're definitely NOT going to be ever running gasoline again then there are 1 or 2 adapter kits to choose from.

Use the site links below, and then browse whichever area you want as there are many options there. The last link listed takes you through all the different engines by make & model #'s.

I would also shop around locally where you are in LA, as you might be able to get that adapter kit for a lot less then the $227 to $267 they are asking for there at that site.

If you don't see your exact model # (or kit) there call them on their 800 toll free # listed at their site.

Also - if this site doesn't meet your expectations customer service wise at least you will have a starting off point with the wealth of information supplied there!

Load it the light, fan, motor, etc that consumes power

Typically, 120 volt incoming hot line is connected to black, white to neutral, ground to green...
Then load has 2 wires + ground ... the white connects to neutral, black connects to load wire, and ground to ground
