You came pretty close to answering your own question there.

Too much choke (choke plate fully closed) and it will fire one time and die.
At that point, it's flooded. After that, the plugs are wet with fuel and further attempts to start it without opening the choke all the way will be almost futile. With the increase in fuel with the choke partially closed, the engine needs more air to mix with the fuel. That's where the fast idle comes to play, it keeps the throttle blades partially open to allow more air to mix with the fuel.
Summertime is coming, so you will need to use the choke less and less as it warms up for the next 7-8 mo. It just takes practice on how to use it. I even have to get used to using it every winter when it turns colder because I forget how the engine responds to the choke. Air temp and the temp of the engine has a lot to do with it also. Everything is different at 2* than it is at 32* and less choke and fast idle is needed. During the summer when the air is 60 or 70* degree's at night, I don't even need to use it.

Another trick you can use is remove the air cleaner and pull your choke button all the way out. Loosen the set screw on the choke arm and move it to where you can just get a pencil between the choke plate and the air horn and tighten the set screw back down on the cable wire. This way, you can pull the choke button all the way out when you start the engine without closing the choke all the way causing it to flood the engine. The choke button won't go all the way back in but it will keep you from over doing it and when you do push the button in as far as it will go it will still open the choke plate all the way after warm up.

For everybody else, It's too late. When I installed the manual choke, I threw out the electric choke. And the car is so close to dying I really don't feel like salvaging another one.

The car should fire before it floods. If it fires a few times then quits fireing it could be flooded. Make sure you push the pedal down a little before pulling the choke cable or else it will hang on the old fast idle cam and bend the linkage holding the cable or the cable will slip out. Pull the cable and make sure its full closed. when it fires then start pushing it in til it starts to run smooth. Leave it out a little til warmed up. TOOO, bad you didn't get on here before you tossed the auto choke... they work great if you know how they work.

Thank you all so much for your help. I think i'm really starting to get the hang of starting this old boat. Just to recap; I should press the petal down at the same time I pull the choke, turn the ignition, and when I hear the engine fire, push the choke in little by little until it starts?

I have seen hundreds of those conversions over the years and without exception, they are junk. It is WAY easier to make a stock choke work than it is to keep one of those conversion kits working. Kinda preaching here but why would you not just fix the automatic choke that was on it?
One thing you might try (forgive me if this has already been mentioned) is to take the fast idle cam and grind the steps off it so it is a smooth ramp. With the steps on there you only have to pull the choke once without depressing the gas pedal and the cable will slip and the whole adjustment is gone.
