Spray Tubes

From left to right, 4 Stroke , 2 Stroke , Norton , Triumph



As a general rule the most noticeable difference between a 2 Stroke and 4 Stroke carburetter is the spray tube, the brass tube visible as you look through the carburetter bore. 4 Stroke spray tubes are cut off straight, 2 Stroke spray tubes are cut off at an angle sloping towards the mounting flange. Some later 850cc Norton Commandos use a spray tube with a square cutaway step while Triumph Triples use an angled spray tube cutaway from the mid point of the spray tube rather than right across as in the 2 stroke version. 2 Stroke and 4 Stroke bodies are not interchangeable and will not run correctly if used on the wrong type of engine.
