If it runs fine for half an hour, it's probably not the carb... Though I say probably hesitantly as it very well could be.
Quickest test for the carb is to choke it a little while it's having difficulty. Half way should be enough - but play around with it. If it improves, then it probably IS the carb... (not getting enough gas through the carb - needs cleaning)
But if it doesn't help - I'd check the coil. That's what I'm guessing the problem is.
I've read janicholson's recommendations here of feeling the coil to see if it's hot. They all get hot, but according to him, almost too hot to touch. I've never felt one like that, but I trust his word.
You can also pull a plug wire while it's running and check the spart against the engine. Look for a good long blue spark. If it's weak, the coil's probably bad.
