You are supposed to disconnect the vacuum line at idle like you are doing.Make sure you are plugging the port on the carb after that step.The timing should not change when you unhook the vacuum line,there should be no vacuum pulling on the advancecan at idle hence the lack of change in your timing when you undo the line.
