Any chance you have a timing light to check timing of the spark plugs? I once had a johnson 50hp that after a trip to canada was off on it's timing. I couldn't keep it running, and when it did, it idled rough. Checked the timing and found it was off a little...once adjusted, that motor barely took a turn of the key and it was firing when warm and purred like a kitten. There are times I miss that motor....it was rock solid!!
So...Just thinking that might be something to check....
It might be just a carb adjustment as well. If you pull the plugs are they wet? If so, it is running a tad rich, or it might just be something as little as an idle screw that needs to be turned up just a touch...
Lots of things to check, so I am pretty much talking "tongue in cheek" here...but hopefully it gets you in a direction that helps improve the situation.
