I have a 1989 johnsonn 20 outboard that pisses me off for the last two weeks.
This motor has been sitting for 3 years without running. A few weeks ago we decided to give it a spin. We used the old fuel that was almost as old as the motor had been sitting, 3 years. We went to lake simcoe, and after some time we managed to launch the boat. After that it was some trouble and time before we got er going. It would idle so slow that it would quit. It ran ok otherwise. Next day I made new fuel and went to lake simcoe again. This time it would idle properly and ran very well. Ok, now that its going well we took it to moon river to go camping. Started as before, lots of cranking. Idled well, but when I went past 1/4 power, it would cut in and out as if it tried to jump off the boat. It sounded like it was turning on and off. anyway, the campsite was not far from the marina so we got there somehow. sometimes i could run full power for a minute or soThen i noticed that a screw was filled over with silicone and the silicone came off. so i put tape over the screw and it ran very well at full power. when i came home, replaced the tape with epoxy. I thought that was the fix. I was mistaking . same symptoms as before . tried carb cleaner with no luck. before at times i could run full power but now i cant.
HELP ME PLEASE BEFORE I GET SO MAD I BUY A NEW ENGINE
