Hello all,
This is my first boat/outboard but have worked on cars and small engines for many years.
The boat I purchased was in storage for 10+ years and was sold without the motor but when talking to the gentleman he said the motor was remove because it was locked up from sitting for so long.
I told him that sometimes you can free them up and still use them, he said if I bought the boat he would throw the outboard in so unfortunately I dont have any history on the outboard.
To get to where I am now I filled the cylinders with marvel mystery oil and let it sit, topping it off every few days after 2 weeks tried to break it free and it turned over relatively easy.
Pulled the carb off and cleaned it and installed a rebuild kit, but it was pretty heavily oxidized. I also replaced the water pump.
When I tried to start the motor it started right up with very little fuss, revs, and there have been times when it seems to run pretty smoothly but normally it will run pretty rough and then "fart or sneeze"( I've seen what I think to be happening referred to different things while searching online) and then die normally.
I have checked compression and got 125-126 on each cylinder just to check the health of it.
I've pulled the carbs 3 times assuming that I had missed something but now I'm starting to think there may be an issue elsewhere but I'm not too sure where to start.
One question I do have is that although I rebuilt and cleaned the carbs and checked that all passages were clear I did not remove and replace the soft core plugs, at the time of rebuilding it I had not seen a carb where those were replaced during the rebuild. I can go back and do so if that could be the issue but my thought process was if the passage is clear it shouldn't be an issue. Please let me know if I am mistaken.
Here is a video of it running, granted this is probably the best it has run yet. The only things I have done as far as adjusting is using the screw at the top of the carb.

Thank you in advance for any assistance!
