Re: 9.5 1969 Evinrude
I think when reload says "holding the intake to the carb closed with my hand" he means essentially to try choking it so it pulls fuel. As far as the rebuild, it's not hard, and those little carbs are simple to remove and rebuild. See pics of my 1971 Johnson 9.5 HP carb I just rebuilt and hopefully that helps some.
The first pic is of the disassembled carb. The top part is the base containing the float chamber and is screwed to the intake with 5 bolts. To the right of that is the high speed jet and a drain screw. The bottom part is the carb itself, attached to the base with 4 bolts, the cork part is the float, just to the right of this is the brass needle and seat that allows fuel into the carb. When it gets full of fuel, the float rises and pushes up on the needle and shuts off the fuel flow. The right of the needle seat is the high speed/main jet pickup tube. Between these two is a port for the idle mix. The big rod shooting out to the left is to open the butterfly on the carb, to let more air in, so it pulls fuel into the cylinders. The roller on the end of that rod rubs up against a cam on the magneto base just under the flywheel and open the butterfly on the carb when you twist the throttle.
The second and third pics have an arrow pointing to the idle jet. It should be set 1 1/2 turns out after being seated to start. When you take the carb apart, you'll want to make sure and blow out all the little ports with air, or maybe even soak all metal parts in a carb cleaning solution. The main jet typically has a hole .048 inches in diameter and you can check with a drill bit and calipers. HTH, and a manual is good to have, even one from a library.
