Question about Sport & Outdoor - Others
1974 johnson outboard motor 25hp stalls when trying to plane out boart points caberator fuel pump replaced .motor start and runs ok at three quarter speed but stalls out when hiting high end
Not familiar with that specific motor but had similar vintage smaller HP Johnsons. From my experience it sounds like it could be that the high speed carb adjustment is too lean. What I would try is running the backing off the high speed screw 1/4 turn to 3/4 turn, then test. If works better, screw back in in 1/8 turn increments until the problem recurs, then back out 1/4 turn and leave it there.
