Methods of Conversions

There are 3 Methods of Conversions for:
Small Engine Propane Conversions &
Small Engine Natural Gas Conversions

The three methods of conversion all use a venturi to produce the vacuum, which opens the fuel controller and allows gas to flow into the air stream. Specially designed venturis are supplied with adapter and carburetor conversion kits.



ADAPTER CONVERSION The most popular and easiest to install

Generator Dual Fuel Propane Conversion Adapter

Cost and installation time of the adapter method usually fall between the other two methods. The carburetor adapter is installed between the gasoline carburetor and the air cleaner. The adapter method should be chosen for dual fuel operation or for the option of quickly converting the engine back to gasoline in the future. Installation sometimes requires the mounting of an idle plate between the gasoline carburetor and the engine.

Generator Tri Fuel Natural Gas Conversion

The LP-gas and natural gas carburetor kits give the best consistent power and performance and are the easiest to install. You simply replace the gasoline carburetor with a new carburetor containing a correct venturi for the engine and application.  However, models available are limited to some older Kohler, Onan, and Tecumseh engines.

*Idle plate is not needed for generators.

Propane Conversions for Generators



SPUD-IN CONVERSION This method has been phased out, the adapter method has become the easiest, and you are not modifying the original fuel system with an adapter.

Dedicated Propane Conversion

The spud-in system is normally the lowest cost method of conversion, but not necessarily the easiest. We have done everything possible to design our fuel tube so they can be easily installed.
