While installing a new carburetor on my 1963 Avanti R2, I discovered that the linkage from the bell crank to the carburetor consists of a tube with a spring-loaded plunger. The spring tension is quite high so it is unlikely that the plunger ever even moves in the tube. This part of the linkage does not function to keep the carburetor throttle plates closed - that is handled by external springs. So, what is the purpose of having this spring-loaded throttle linkage?

When the choke is applied, there is a lock out tang that prevents the secondaries from opening. The spring allows throttle linkage travel to continue, so the transmission kickdown will still function.Bez Auto Alchemy
