Okay, why do you want to replace the carb?
I don't want to sound like a jerk, but the reality is that you are still learning how all this works and chances are the problem isn't the carb, it's you. Now, that's kind of harsh but that's something you need to realize. You're getting some good help here and if you sent the motor into HPI and they worked on it, I can promise you that it came back to you in a working condition.
Go through the steps I gave you before. Go through them exactly as I laid them out even if you think you've covered them. Go through them with a positive attitude and you will find your problem.
