Jim,
Since both plugs fire at the same time, it doesn't matter which lead goes to which plug.
Second, I would richen the top end by one full turn and try it again.
It sounds like you are too lean.
OK thanx, wasn't sure of the firing order so that's why I asked.
Engine is no longer in a plane so will have to wait to find new home or mount on a stand. Thanx for advice.
