I'm looking for a pic on the net right now of what I am trying to explain.
There is a picture of the engine of Jim Miles' Magic Muffler Fiat in the Winter 2015 Elapsed Times magazine page 35 that
shows a cable attached to a bellcrank at the rear of the injector housing that looks as if it would be activated by the gas pedal.
The pic also shows another cable attached to a bellcrank on a fitting on the driver's side of the cam driven fuel pump that goes back up the side of the engine towards the rear of the car.
I'm hunting,,,,,,
