Steps to convey gas generator to propane are:-

The first step involved in mounting the kit is removing the air cleaner and fitting an adapter (venturi) with a propane fuel port on the bolts that connect the air-cleaner base to the carburetor.

This will usually require using a couple of bolt extensions (provided in the kit) to allow remounting of the a/c.

The second step is to mount to the frame of the generator a regulator through which the propane passes on its way to the carburetor.

There are a number of brass fittings that must be secured to the adapter and regulator, both of which are made of aluminum, so these fitting threads should be wrapped with Teflon tape and then snugged down.

You must take care not to crank down too hard on these fittings, or you’ll find yourself in a real bind with stripped aluminum threads.

After the adapter and regulator are secured, with all fittings tightened, you attach a hose that runs from the regulator to the adapter and one that runs from the regulator to the propane tank, and you’re ready to fire that sucker up.

Prime the system by pressing the little button on the back side of the regulator and crank the engine, using the adjustment screw on the regulator to smooth out the engine and set the rpm that suits you.
