Did you clean the carbs before or after it "ran perfect"? If it ran fine 2 weeks ago i would not change the plug heat range. If all three plugs are gas fouled i would check for an improperly adjusted choke. If it is just one or two plugs maybe check for a stuck float in the carbs.

Usually because u probably didn't run it very fast or very long, plugs get a build up on them, which is why I rarely run my machine in summer. Change the plugs and give it a shot, don't run anything hotter than a br9es. You could try a BR9EYA though. They have a little V cut in the electrode, which supposedly keeps them from fouling. It's what I use.
