Hi
I'd like to make a correction on the difference between the Morris rib
case and the Spridget ribcase gearbox. On the Morris ribcase, it is
referred to as a wide ratio box and all the gears are evenly spaced.
First gear is much lower than on the Spridgets and second gear on the
Morris Rib is close the same as the Spridgets first gear. The Morris Rib
is also a bronze bushing vs the needle bearings on 2nd and 3rd gears.
Now the smoothcase on all but the later sprites, they have the big gap
between 2nd and 3rd. Makes you wonder sometimes if you skipped a gear
while climbing a hill with a 948! Especially in a Morris as it weighs
about 500 lbs more than a Spridget!
