One simple thing to try is to pull the choke rod out while it's struggling. See if it runs any better. May not have to do it all the way, you may find half way out is good.
If you find any improvement at all, then your problem is almost certainly blockage in the carb.
Choking the carb makes it run richer - more gas in the gas/air ratio.
So if choking it helps, it means in its normal unchoked mode, it's getting plenty of gas INTO the carb to run fine, but it's just not getting enough gas OUT of the carb into the engine.
If choking doesn't help, it doesn't prove much, but you may want to devote a little time to checking ignition components too while trying to find the source of the problem. It could still be the carb, but usually means you're not getting enough gas INTO the carb to begin with. (line blockage, floats not adjusted properly, leak in the float, etc)
I think you'll probably end up having to clean out your carb.
It's pretty easy.
I did a quick search and found this link for a carb on a super a - it's not exactly a great "how to" but it will show you what to expect if you pull your carb and take it apart.
