    1971 25hp Johnson running rich

    ain't saying it is.... but I would check the crankcase drain circuit to ensure the small flapper valve is not stuck and the hose is not blocked or crudded up preventing the lower crankcase cavity from draining excess fuel oil and causing an overly rich lower cyl. behind the...
