15 Minute – Propane Lawn Mower Conversion

The choice to convert from gas to propane is based on the greatly Increased engine life,  lower maintenance costs, Improved engine performance and a significant reduction in air pollution. The conversion allows for the engine to run on either gas or propane (dual fuel) if ever needed. With the growing problems mounting  with the use of  Ethanol and the nearing increase to 15% of Ethanol in fuel this conversion makes even more since.  The kit used is from AltFuel, LLC. and available at www.robinsonoutdoors.net the mower is powered by the Honda 5.5hp GC Series engine. I selected the  5 to 9.5hP Honda GC engine kit which includes the regulator, intake adapter plate and supply hose. The installation requires the carburetor to be removed via the three screws on the air cleaner cover and replacement of the black insulator behind the carburetor with the aluminum adapter plate with the propane jet and supply line connection. Next the mounting of the regulator and tank on the handle and the routing of the fuel supply line to the carburetor from the regulator.
