I have a Tohatsu 9.8 4 stroke
I have a Tohatsu 9.8 4 stroke outboard with under 20 hours on it. I primarily fish lakes above 6000 feet and have the high altitude jets installed.
The top spark plug is really black and sooty but the bottom plug is clean and the engine seems to lack hp. Any suggestions
