1982 Johnson, 7.5hp, Idle Speed Setting

[jgmcbee]

What is the procedure for setting/adjusting the idle speed of this motor (Model 8RCNR)? Is the "knob" at the end of the throttle/tiller handle a throttle adjustment of some sort? I do not have a tachcometer to measure RMPs.
Thanks in advance for your advice.

the button on the end of the tiller, is the kill button. idle mixture is the top needle on the carb, idle speed is adjusted on the cam. http://forums.iboats.com/showthread.php?t=299680

Thank you for your quik reply Chief. The kill button is surrounded by this "knob" that I wrote about. It will turn independently from the throttle handle. The sequence is first the rubber throttle handle, then plastic "knob", then kill button in the end center of the "knob". The control panel of the motor has a "Slow Speed" adjustment that is linked to the slow speed carburetor jet.
