My Dad's 2000 Johnson 25 HP (J25RSSE) will not get full throttle when on water.
It would not start so I began with new gas, seafoam, cleaned out all fuel lines, cleaned fuel pump, rebuilt the carb, (twice) (sprayed with carb cleaner, soaked, and blew out with air hose.) The carb was filled with junk, so I this would be an easy fix. Also checked compression, OK.
Before servicing, i was barely able to get it started, and once it was I did, it was coughing, sputtering, and running very rough.
After servicing, and adjusting, the sputtering was gone and it idled smooth. I am able to get it to idle up from idle arm, but when in water and give it throttle I can't get any speed out of it.
This seems to be some kind of fuel restriction problem to me but was wondering if anybody has any ideas on what the problem may be, or what i may have overlooked.
Thanks for any help,
