If you have to choke it to run, it is running too lean. Sounds like your distributor is ok, once you replace cap and rotor. EI is likely ok, if your spark is ok. Carb is probably ok as long as you reamed out the idle jet and other spots with a thin wire. If the idle jet was clogged, it wouldn't idle, but your problem is it won't accelerate. A clogged main jet would restrict fuel. Clogged ports in the side of the throttle throat will restrict acceleration.
Timing may be an issue. Sometimes turning the distributor a bit will enable it to start. Turning it clockwise retards the timing, and richens the mixture, from what I understand.
Did you reinstall the carb with new gaskets? If there is an air leak at the manifold gasket, the engine will run too lean, which could explain why it only runs with the choke closed. Also, make sure that your idle adjustment screw is one turn out from its seat, to begin with. Turning it out makes it run leaner. Always be sure of your firing order.
This forum never ceases to impress me, you are at the right place. Happy sailing!
