With kind advice from this forum I've become fairly adept at dismantling and cleaning my carb in a Mercury 3.5. Anyhow although it guns and starts fine I have two issues.
1. When move at full throttle for more than 1 minute it starts to stutter and I have to throttle back. I'm assuming the float isn't set right and as the chamber of fuel empties it is then not allowing enough fuel in to catch up with consumption.
2. When I turn the outboard off but leave the fuel tap open it floods itself. Again probably float not adjusted and therefore not quite blocking the fuel off when chamber empty.
I've tried bending the little metal flaps so that when he float is up it pushes against the needle and when it's down allow the needle to drop a bit. I suspect I need to be more precise than this but wondered exactly if there was a way to know how much angle to set them at?
