 If you have Dellorto Carbs, (did Canadian cars have Dells?) the Unisyn is not sensitive enough to take decent readings. It also alters the operation of the engine because it blocks the airflow to the cylinder being measured. Search for 4 tube manometer in old posts.

The Strombergs two cylinders per carb make the Unisyn readings possible. If you need to, adjust the carbs at 1600 rpm and reduce the idle afterwards.
