What does this lever do?

[240znz]

First post on my Zed.

There are two levers that are in the console in my 71 240Z. The left hand one is the choke (has typical butterfly symbol) but the lever on the right has got me stumped.

It is a symbol that I can best describe as a butterfly in a venturi with three what looks like squirts of some thing at the bottom of the venturi.

My Haynes manual turns up on Friday but its bugging me.

Any ideas:cross-eye

Its the hand-throttle. The lever was deleted on later models.

Yep!

Old-school cruise control, baby!!!

They took it off the later models cos it's potentially pretty damn dangerous.
