Tension spring for Sofim-type and similar all-speed governor levers (governor mod).
A stiffer spring that fixes the usual issues with the springs found on Sofim and similar levers: excessive governing and a low cut-off RPM, which often hold these levers back on car pumps.
With this spring, you get results similar to car throttle levers while keeping the benefits of the long 20mm lever.
Spring sold alone.
