If it runs fantastic, leave it alone.  It is impossible to read plugs with this new fuel, it just burns too clean.  In any and all cases, go by how the engine performs.  If it were lean on primary jetting, it would "surge", hesitate, stumble, or be "flat" on power on the primary side only.....Cliff
