Ok, don't listen to anything I just posted. I went back out again and sprayed more carb cleaner all over that damn assembly and finally pinpointed the leak! Its where the carb is connected to the body...but what I don't understand is why this never happened when I first rode it around. I'm going to stop by Napa tomorrow and pick up some of that hylomar and seal that area up really well. Hopefully this is the last thing I will need to do before it was running like when I first built it! Can you believe this engine has less than 2 hours on it? I'm not digging the quality of these Huaseng engines.
