I'v alway been meaning to ask about the nonchalantly named Throttle Control knob described in the operators manual. This thing had to have been deadly! Did people use it as an early form of cruise control? Considering the road conditions and construction standards at the time (and even now), I cant imagine it! Perhaps in the wide open plains, it might have been feasible? But here in Boston and Greater New England, Id give the life expectancy of about a week. Is it even legal? Grand fathered in like seat-belts? What about Hot-Rods? Good thing mine is unhooked. Otherwise Id probably try it! What Say Ye?
