^* 427/400 Yellow Secondary Carb Spring

[Jack C.]

Can someone share their thoughts as to when was the yellow secondary spring added to the 68 model year tri-power setup? My car is a January 22, 1968 build.

Don't know about the date change but my April built tri-power only has the yellow spring.

Thanks. The AIM shows only the primary spring and the TIJM notes that the yellow spring was added later. I'm going for Top Flight judging in September and would like to get all the points I can and it's down to all these little items that I wanted to be sure on.
