We are now processing all orders through our official Motor Snorkel Site located at You may be directed to to find a kit that works for your Generator and Engine.

The site that you are currently viewing is full of useful and updated information about converting your generator using one of our traditional generator conversion kits or, our newest product, Motor Snorkel. We have replaced our Kit List Page for All Generators and Engines with our convenient Conversion Kit Finder, which will allow you to quickly and easily find the correct kit to change over your gasoline only generator to become a Propane Generator, Natural Gas Generator AND Gasoline Generator.

Motor Snorkel is the patented, revolutionary, device that changes your gasoline only generator into a hybrid, tri-fuel machine.

A brief history

US Carburetion is the industry leading authority on conversion kits to change your gasoline generator into a propane generator or natural gas generator. For 30 years we have been converting more generators than anyone else.

In the beginning, our fastest moving kits were for generators using Briggs and Stratton Engines. We originally developed kits that we called Type 1, Type II, Type III, Type IV and Type A and Type C kits.

These classic style kits require significant installation effort. You must be prepared to add stud extenders, cut the crank case tube and even to cut the frame! We set out to develop a brand new system. A revolutionary approach that was so simple to install that ANYONE could do it within minutes.

Traditional Kits ( Like those sold by our competitors ) Require Complicated Installation.

Dependable When It Counts: Propane Generators and Natural Gas Generators.

You can count on gasoline . . . to let you down!

Gasoline is not a fuel that professionals ever choose to use on backup generators. Hospitals and other large facilities "never" install a gasoline back-up generator. They always use natural gas or diesel. Gasoline has a very limited shelf life and will actually cause engine failure. Worst of all when power outages occur due to ice storms, hurricanes, tornadoes, earthquakes and all other disasters, the first commodity to be hoarded is gasoline. Sadly, long lines (even fist fights) and rationing at gas pumps are a common occurrence during many disasters. The hurricanes that have devastated the eastern and gulf coast of the United States over the past 10 years and Hurricane Sandy were sad proof of that.
However, working along with FEMA, we were called upon to be of assistance in helping in areas where gasoline was not even available to run generators. Propane generators, and especially natural gas generators, were more plentiful and just the ticket to keep the lights on and the crews working.

Unfortunately, as some have learned the hard way, if not used often enough, gasoline will gum up the carburetor and will render an engine on the emergency generator useless. Do not get caught with a gummed up carburetor that will not allow your engine to run, on your gasoline generator that you cannot even get fuel for, when you need it the most.

Now that you have invested in a backup generator, make sure that it runs when you need it the most. Modify your Generator to run on propane or natural gas or even keep the gasoline option if you like and have the option to run all three fuels on the same engine!

Propane and natural gas can save you time, money and aggravation. 

Our do-it-yourself change over kits allow you to run your gasoline generator on propane (LP Gas), natural gas, or all three. Propane and natural gas are truly a backup fuel for a backup generator.  Your engine will last longer, start better in cold weather and even start next year when you go to use it in an emergency. The best part is, with one of our do-it-yourself kits you can change your engine from gasoline to propane or natural gas all by yourself. Wouldn’t you rather have a dependable when it counts propane generator or natural gas generator?


Why use propane to power your generator?

If you have propane available you know you can store propane for years because it does not gum up, go bad, or pollute the air like gasoline does. You can use the 100# (24 gallon) cylinders, little bar-b-q grill type 20# cylinders, which is equivalent to 5 gallons of gasoline, or big tanks like 250, 500 and 1000 gallon ASME tanks.


Why use natural gas to power your generator?

If you have Natural gas available you would certainly agree that it is probably the most dependable fuel on earth and virtually an unlimited supply.  Natural gas is always there.  It does not gum up or go stale like gasoline. 


Here are many more of the benefits:

  • bullet Propane and natural gas powered engines provide the same power as gasoline.
  • bullet Longer, uninterrupted run times!
  • bullet Connect to big tanks or to your natural gas pipe line.
  • bullet Your generator will last longer because of larger fuel supply and less running out under load.
  • bullet Clean burning Alternate fuel will help extend the life of your engine life.
  • bullet Eliminate the Dirty Port that gasoline carburetors have that shortens the life of an engine.
