I usually use my Bing carbs book for CV carbs but I today I was trying to find info for my 1968 R60/2. On page 27 and 28 of the book there are " /2 Exploded Views " diagrams for T-77, T-115, T-XXX etc etc but I don't see where those codes are cross referenced to the chart on the insde front cover.

My carb numbers are 1/24/133-134 so where in the book are the T-XXX codes explained?

TIA
