hi, I published some new videos on this outboard, I fitted it with an oversized 5 hp carburettor, bringing it to 6 hp and on the 3.5 bringing it to 4.5/5 hp including aluminum propeller
I have to say that the power has really increased
The idle screw is not that one, but it is on the other side, it has a spring and is placed at the top, where the guillotine opening is
The one you unscrewed and cleaned is the one from the air/fuel mixture that enters when the accelerator is closed

Thank you for your videos, I've learned so much about this motor from you. Definitely good to have these sorts of tips in our back pockets if we ever come across the same issue. ps. I did my first winterization last year following your tips, and my 6hp tohatsu almost started on the first pull this spring (roared to life on the 2nd, and was super happy)!

That piece you took out is call a jet, it allows a certain amount of fuel into the carb. On a car you can replace these with different sizes to get more fuel. The piece behind the cap is the air fuel mixture. You use this to adjust how much air gets to the car. Generally you adjust this to the highest rpm you can get at idle. More fuel more air more power but you can take it to far and flood the engine

Does this motor require the bucket of water? Oil cooled engine... Or does it have a water impeller like most others that has to be protected? I just don't see on the bottom of the unit where the water intake is located...thought it didn't need to be in water to start and adjust things. I could be wrong, easily. Tks
