" I have a 1978 johnson 70 3 cylinder and it has idled
rough for te past 3 years I have tuned it up with
new plugs, rebuilt carbs I have 3 new coils on it
a new fuel pump and the compression is around 120
on all 3 . I did all of this work in the last couple
of years . boat was in rough shape when I got it.
I think it could be the reed valves, it also gets
a miss right before the engine smooths out at high
rpm. any ideas I would like to resolve this.
thanks "
