9.9 johnson four stroke


lloeg

Question

I have a 1999 johnson 9.9 fourstroke that recently started to stop running in neutral.
changed plugs and didn't help. changing idle speed diddn't help.
it seems to only be running on one cylinder at idle, but suddenly increases rpms as I add throttle (linkage is fine) and runs fine at moderate to hign speed. then dies at idle. Any ideas?
