Honda 40

I have a 40hp Honda and I simply drain the carbs every fall.
There is a screw on each carb that you back out until the fuel starts running out. I just leave it for a couple of hours and tighten them up.
I'd suggest checking out YouTube for better instructions but it's easy to do and has worked for me since I got the motor about 8 years ago.
