"Posted here couple days ago. 92 johnson 70hp. I checked carbs, seafoamed and the outboard is running much more smoothly. I still have a stutter under acceleration and at higher speeds. the bulb will not stay hard, my external fuel filter drifts down to about two thirds full and then I get the stutter. I can repump the bulb to stiff and away we go which makes me thik its a air leak or its a fuel pump not being able to pull enough fuel but why the soft bulb? How do I test for an air leak aside from looking for any clear problems. I can't see anything. I dont get bubbles in the external filter. Is there any sure way to test for air leaks and also how do you test a fuel pumps output? Any ideas or help will be appreciated."
