With my '70 TR6 I have come to the conclussion that the 3/32 gap
(using a drill bit to set) just doesn't seem to work for performance.
I felt that it allowed too much play with the throttle and not as
quick a responce when pushing the gas peddle. I no longer use this
measure to adjust the lever but rather visually set it so the tongue
is slightly gapped.
