You know I had this same type of issue on my 50 HP Honda. I ended up giving in and taking it somewhere as at the time, my experience with outboards was extremely limited. What it ended up being was the low speed jets where clogged. I was told that no matter how hard I would have cleaned, I would never have gotten them to where they needed to be to run properly. The root of my problem was that the previous owner had left bad gas in it. I was told at the time the only way to fix the issue was replace the jets. After doing so the motor ran flawlessly like it was brand new. The jets are fairly cheap, and I figured that since the gas sat in the carb, that all the jets were effect, so I replaced them all. You may look into this, as this could be the issue.
