Hi all, working on my old Nissan NS5B, and was trying to get idle smoothed out, but it’s behaving odd... I turned adjustment all the way in, and backed it out only a fraction (any more than that, and it would roar and not come back down). I’ve attached a video of how it’s reacting. When I hit the gas, it takes forever to come down again.
Now, this is my first outboard, so bear with my inexperience. Oh, last thing, carb is brand new.
