I think there is some other problem. That carb shouldn't be causing you problems. If it was always too rich, I'd say replace the power valve, but that doesn't seem to be the problem.
You need to give everything a thorough going over, from manifold leaks, to adapter to carb base leaks, float level, idle adjustment, etc. In warm weather you should not need much choke or for more than a moment to get it to fire up. You have some work ahead of you.
