As an aside, a 914-6 also has a hand throttle. Since it has a throttle cable
(not a rod) in the tunnel, the hand throttle uses a push rod that actuates
an extra piece on the throttle bell-crank at the pedal assembly. This
914-6-only bell-crank was also used with the (very rare) 914-6 Sportomatic.

Part 27/1 (red underline below) is the 914-6-only part 914.423.250.02
that needs to be exchanged in a 4-cylinder.
