When converting small engines to run on propane or natural gas, there are three different methods of conversion that are used. They are as follows: (Note, the adapter method has become the most popular)

1.) Adapter method, the most popular method (tri fuel & dual fuel propane conversion & natural gas conversions)

2.) Replacement method Replacement Carburettor for all Fork Trucks (limited availability for generators)

3.) Spud-in method. This method has been phased out and replaced with the adapter method
(it was a straight propane conversion, non-reversible)

The adapter method has become the most popular because it's the easiest conversion to install on a concrete saw, welder, or generator, no drilling of the carburetor required, and it's less expensive than the carburetor replacement method
