Generator Tri Fuel Conversions and Dual Fuel Propane Conversion Kits


Parts in a Dual Fuel Conversion Kit

Parts Included in a High Pressure Dual Fuel Conversion Kit in the photo above

To install a dual fuel or tri fuel adapter conversion, which is simple, you would add the stud extenders or longer studs that are provided with the conversion kit. Then slide the adapter on the studs to the air horn of the carburetor. Install the air filter assembly which will leave the adapter between the air horn of the carburetor and air filter assembly. Find a convenient place on the frame of the generator to mount the Beam T60 2 stage high pressure demand regulator, or the Garretson KN demand regulator for a low pressure or tri fuel installation. The load block for adjusting the air fuel mixture can be installed at the outlet of the demand regulator or at the inlet of the adapter, which ever is easiest access to adjust the air fuel mixture, you can note that in the photo at the bottom of this page. A good rule of thumb is to adjust the load block 4 to 6 turns out for your first start up. You would then press the manual primer on the back cover of the demand regulator to push the fuel to the air horn of the carburetor and start the engine. Once the engine has started be prepared to readjust the load block for proper air fuel mixture until the engine runs smooth and put a load on the generator and adjust the load block for the final adjustment. The governor and throttle plate in the carburetor will still control the speed of the engine just like it did when on gasoline, you are simply using a different fuel at the air horn or inlet of the carburetor.
