Default Symptons of dirt in Engine?

I've put in about 15 flights in the past three days. It's been great. Today, however, I tried to get a little fancy with a low, slow inverted pass with my trainer 40. Well, not a good idea, obviously, but I wanted to put her to the limits. Anyway, it didn't work out very well. She couldn't quite hold it. Did a few kartwheels with a bit of repairable damage. No problem. But upon further inspection, I noticed that a fair amount of guck had gotten in and around the carb. I closed the carb and removed the gunk the best I could, hoping that nothing got directly into the engine. Now, I should note that I've been flying with the O.S. 40 LA. I've never deadsticked with this plane ONCE through two gallons of fuel, and it pulls my tower 40 with a suprising amount of authority. In any event, I know that I shouldn't have tried to start it back up again without taking the engine apart, but I did it anyway (I'm still 10 at heart). Well, she started up no problem, but towards full throttle, it seemed as if it wasn't working at it's fullest potential. Okay, well, I'm probably just being neurotic, I thought. Well, about a minute into the flight, it dead sticks. Not just that, but it is very difficult to get going again, and when it does, it again will not max out at full throttle; and about a minute later wants to quit entirely. I tried to start it again several times, but with no sucess. It sputters a bit and dies. So I headed home. I checked all of the fuel lines, and they are all in tact. The tank is still secure as well. I am hesistant to take apart the engine to clean it out, because I did that with my TH .46 and I don't have proper compression (when I turn to prime no fuel is drawn into he carb.any advise on this matter would be much appreciated as well). Thanks for taking the time to read this post. Thank you.

Best,
