Just an FYI- our excellent JH Shop Manual does list a measurement for timing belt tension- whoo hooo, it's 35 Kp! It's in the RM service pages.

–Update– the Kp (kiloponds, now that's useful) conversion to pounds of force comes out to 77.161 and it actually seems to work, at least on my car.

Later Lotus publications state that 90 pounds is the "correct" pound force measurement on the Kent Moore gauge device, BUT this measurement is for the later, hardened pulleys. The Jensen Healey uses the softer aluminum pulleys, so consider a timing belt tension more appropriate to the material used.
