It is my understanding that nothing other than piping in natural gas. The change will have a slight effect on watts produced vs fuel consumption.

NOPE. you will need to change the orifice (jet) to go from propane to NG. Same as you would for a BBQ, patio heater, stove, oven etc.

My honda generators have been converted to tri-fuel, The NG orifice is definitely different than the propane orifice.

ktmrfs has it right, even though you are using gas "vapors" with propane or natural, they have differences which changes the fuel to air ratio and pressure delivery will be different between the two..

On carbed small engines, it would be better to add a natural gas conversion kit or specifically designed trifuel carb since there may not be any "orifice" to change like BBQ grills and other "appliances".

See HERE

Per link above ..

"Champion 76533 Natural Gas Kit. This kit fits the Champion 76533 Dual Fuel generator and adds the ability to run it on Natural Gas."

That PN kit is from CENTURY FUEL PRODUCTS and is add on kit including a special natural gas demand regulator..

Additional mods to gen frame may also be required and at $169 is not cheap either.

I did find a "Trifuel" carb made specifically for ability to use gas, propane or natural gas HERE for $28 and typically should fit most Honda "clone" engines 6.5HP-7.5HP (GX170-GX200) which is most likely your better way to go!

It IS a "replacement" carb so you will have to remove your existing dual fuel carb.

Found a YouTube video HERE showing a Champion gen conversion using this carb from Amazon..

yup, when I did my honda conversions the purchase options were dual fuel (gas or propane) or tri fuel (gas, propane, natural gas). switching between propane and natural gas requires changing the orifice as well as adjusting the demand regulator. the kit I have uses the stock carb along with adapter plate and an external Century KN low pressure demand regulator.

The kit I have allows tri fuel use without messing with the carb once the kit was installed, but it uses the same century pressure demand regulator.
