the Fast Idle Function does not work on my motor, I have to open the throttle for the motor to start and after I few seconds when the engine is somewhat warmed up I can put it back in neutral and the motor idles fine.

I know this motors are supposed to start up in high revs for few seconds and then go down to the normal Idle speed, but mine doesn't, I also put a new I.A.C valve but still does the same thing, any ideas?

That engine is the Johnzuki model, check your temp switch.

thanks for your reply, I know is the same as the suzuki DF115 but what the temp switch got to do with the fast idle function?

It is one of the controls for the powerpack that turns the timing advance off and on.
