I have a question. I have a 1986 Johnson 50HP and it seems "to me" that it is having a fuel delivery problem. Some times it is hard to crank and when at idle it fine. I put it in gear and it starts to stall out, kinda jump like it gets gas then get deprived of it, and just seems to be kinda starving for gas or maybe bad gas. I checked the plugs and they are fine. I removed the lower carb and it seems to be clean as a whistle, no restrictions and the float moves freely. I havent removed the upper carb yet. If someone could maybe point me in the right direction of where I need to go next I would really appreciate it.
