The average current curves are a direct measure of the coil input. In the case of the four cylinders engine we recommend the simpler and more easily serviced single lever Delco-Remy distributor, as fitted to the Sunbeam Talbot. As this has a four lobed cam we can in this case, obtain a make ratio of sufficient amplitude. Rm{William Robotham - Chief Engineer}/RC.{R. Childs} | ||
