Hello all,
Some may recall a few previous questions I had for the forum about the installation of a throttle cable mechanism in lieu of the original mechanical linkage. I am still inclined to go this route on my car, but before I do I want to at least understand the engineering behind why the original mechanism was designed the way it was.
I have noticed that on most healey race cars the throttle actuation is by cable. The original linkage abandoned. Jeff Johnk's car (which is very fast by the way, with the new DMD aluminum block with the DMD head) uses a direct throttle rod with ball joints from the pedal shaft to the carb throttle shaft instead of a cable.
Is the original design the way it is because of the need to connect the throttle relay for the overdrive? If the explanation isn't the overdrive, I am puzzled as to why such a complex system would be developed when the Bugeye of the same vintage used a cable process.
I hope someone can explain this to me. Thanks.
