Keep in mind that the published changeover points for TR4/4A carbs are by
engine number, not by commission number. I don't have my notes and manuals
here at work to check, but it's entirely possible that CTC72451 has an
engine number consistent with Stromberg carbs. TR4/4A engine numbers
usually correspond fairly closely with the commission numbers, but I've
seen some major factory original departures.
