Re: 1988 Evindrude V4 88hp carb - External ports to inject carb cleaner?
You can convert your primer solenoid to a later version by purchasing Bombardier part 175158, maintenance valve. It can be substituted for the one on your current engine and will permit direct injection of both winterizing fluid and Engine Tuner, a carbon preventing (and cleaning) solution. At a single point on the engine.
