Re: 71' 100hp ..no idle...runs fast rpm (3000+)
Needs more info....lots.
Is it new to you?
did it ever run correct?
How can you start it if it won't idle?
Is it in the water or on the hose?
are the throttle plates fully closed at idle?
when did you service it?
what did you do?
is it firing on all cyl's ( timing light).
etc etc.
