Garretson Propane Adapters are machined from wrought aluminum bar stock, meaning they are strong and malleable. Most comparable adapters are cast aluminum and quite susceptible to cracking or breaking. Garretson Propane Carburetor Adapters use a separate load block as the inlet fitting. It can be positioned in any direction at the adapter or the fuel controller, insuring ease of installation and adjustment. The load block on many other adapters is a part of the casting, often producing additional time and expense of installation. We offer a number of specially designed propane carburetor adapters for most air cooled engines. If you will call us with the make and model number of your engine we will advise you if we have an adapter for the application.
