        <span style=”-webkit-tap-highlight-color: rgba(0, 0, 0, 0);”>My 25 year old 841 Caddigger B&S engine carburetor was failing and rebuilding it did not fix the problem. Internal blockage could not be located. Replacement carburetor was not available so my only option luckily was propane conversion.
        Several companies will sell kits and they are very simple to install.
        I purchased from this company </span>

        Basically the 20 pound propane tank feeds into a manifold adapter that mounts under the carburetor, using a rubber hose and clamp. My old carburetor was still useable as that controls propane flow using the position of the still workable throttle plate.
        The conversion starts instantly and when I want to stop the engine I simply close the propane valve to starve the engine of fuel. The ignition switch is always in the on position. It is recoil start.
        These conversions keep a still tuning engine in service after that original carburetor has failed. And propane actually is a cleaner fuel that increases engine longevity. </span>

            the only down side of propane is the run time is less compaired 20 lb bottle to full tank gas because they do not develop the same power as regular gas . but there is a lota plus’s for propane.

                I will be courious to see if you have freeze up issues with the regulator when it is cold, they do make regulators meant to be used in cold weather appilications tho. When we had propane powered vechicles at work they used coolant off the heater circuit to flow thru the regulator to keep it from iceing.
