hutch mountain has a tri fuel option. It does use a different orifice for NG vs. propane, about a 30 second changeover.
That's not a bad approach either, because you're instantly "dialed in" to the proper fuel mixture as soon as you change orifices.
With the Motor Snorkel kit, you have to remember how many turns to twist the fuel mixture screw for each fuel. (After I got the settings for both fuels just right, I wrote those numbers on a sticker on the generator to help me remember).

no worries about varnish build up in carburetor
oil changes less frequently
spark plugs last a lot longer.
Also, the engine exhaust is quite a bit cleaner on propane or NG - Less objectionable odors, and less carbon monoxide produced.
One major advantage of propane is that a 20 pound tank of it usually runs the generator considerably longer than a full tank of gasoline in the generator would - and if you're using an automatic changeover between a pair of propane tanks, the difference in run-time is even greater.
Of course, if you're hooked up to a residential natural gas supply, your generator run-time is unlimited.
