I have a 1990 Johnson 115 that bogs under load. The motor will start and idle all day long with out issue. The problem is once I put it in gear and try to speed up, the motor will only get up to about 4 mph and then bog down. I have replaced and clamped all fuel lines, vacuum lines and connections from the tank through the pump and into the carburetors. I rebuilt the carburetors so the needles would seat properly. I then replaced all 4 spark plugs and spark plug wires. I have determined that the motor is bogging because it is getting too much fuel. What would cause the motor to get too much fuel if the carbs are clean and rebuilt to operate properly? Is it possible that my motor is getting the right amount of fuel but I have an ignition problem that can’t burn it fast enough? The one thing that scares me is I did a compression test when the motor was hot and my numbers read 125, 110, 110 and 90. I’m thinking my issue may be in the stator or the power packs if it’s is indeed an ignition issue, but I’m afraid to replace those expensive parts if it’s possible that the low cylinder at 90 is the reason my motor won’t run right.
