we have a 1975 75hp Johnson Outboard. If you have been operating at
trolling speed for 20-30 minutes it will stall. If you try to restart
with throttle 1/3 open it will not restart, but if you put throttle at
wide open it starts always. I wanted to try adjusting the idle fuel
mixture, but cannot find anywhere to do this (Type 1 carburetter). Any
thoughts on what the issue is or how to fix it.
