it is a long knob (plastic) with a lock nut (plastic) and it is located under the flywheel to the side and it goes conected to a bracket who moves open the carburators .

The all plastic knob assembly sets the synchronization between the amount of spark advance and the throttle opening. There is a procedure in the service manual about it. If I remember correctly, with the motor in gear on the water and the rpm exactly at 900, you set the knob to just start the timer base advance movement.<br /><br />On later motors, there was a stainless steel screw and locknut sticking out that advanced or retarded the timer base to set the idle rpm.

Wolf - In order to get any meaningful help here you at least have to tell us what motor you have. What you are referring to, I think, is the timing adjustment. It is usually done in conjunction with setting and adjusting the carbs - called sync & link. Both are best done by using the shop manual for your motor.
