Really, I always loved it for my motorcycles

Summer is short, a new 4160 is cheap compared to days lost not on the water. If the carb is original I would recommend buying new (Jegs was the cheapest when I looked) and rebuilt the old and reuse on a car or something that isn't so critical like a boat.

What kind of intake do you have ? The previous owner of my boat changed the intake and it was designed to run at 1500+ rpms. When I put the correct intake on it made everything great. I too spent a lot of $$ trying to fix the carb when it was fine all along

Be careful of seafoam, it does more harm than good...

What is the issue Sea Foam?

We started using it after we started having issues with the ethanol in the gas. For the most part, Sea Foam seemed to clear up the rough running but this year my boat is worse... (I will start a new thread for my issue)

got the boat running good, granted I had the idle mixture screws way out. Ran wonderful the hole day. Went out Sun and would not stay running in idle! WTF!!! Anyway got to the sandbar and opened the cover after inspection found 1 idle mixture screw completely missing. So since I had to order and am waiting on that part I am just rebuilding the carb all together. Ahhhh I love boats!
