I have a 93 25 Johnson that used to run fine however, it sat with out running for a few months. When i recently tried to run it will crank and idle fine but when i go to run the boat will get on plane and run for about 30 seconds then bog down and shut off. It then requires many pulls to get it to crank again. The carb and bowl were removed and cleaned with carb cleaner, new gas lines were installed, and new sparks plugs. However the same problem still continues. Could the high jet still be dirty?
