I am unable to find any settings on Weber Carbs 40 DCOE 151 being used a Triumph TR4A. The Weber Books only show 40 DCOE 18 on a Triumph TR4A and do not tell you if the two carbs are the same or not. Does any one know if the settings are the same or is there a table of settings for the 40 DCOE 151 when used on a Triumph TR4A?
