Agree with Mark Lake. Only way having the magneto energized could make it run better on diesel would be if the compression release valves are leaking. Otherwise, the auxillary combustion chamber would be completely isolated from the diesel combustion chamber, and leaving the magneto energized wouldn't do anything except erode away the spark plugs. Might try a compression check, if there isn't much difference in compression between the gas & diesel positions it would indicate that the compression release valves aren't closing completely.

newpuller, just for future info, the WD-6 is a gasoline start diesel, which is a rather unique configuration. It has a third valve in each combustion chamber which opens to an auxillary combustion chamber to lower compression and provide access to spark plugs for starting like a conventional gasoline engine. Once the engine has warmed up a little, its switched to diesel by closing the auxillary valves and applying throttle to the diesel injection pump. The magneto is only used while its running on gas; once on diesel it uses compression ignition just like any other diesel. ;)
