I found certain retailers of the Honda 2000 will sell you one converted to run on propane from gasoline. Like the propane dinghy outboards (Lehr), NO gum in the fuel system. There is a cost from lower BTU in propane than gasoline, but if you already use propane for the Magma, you have the fuel (hopefully in the right spot).
