Mine did the same thing. If I had the GAV adjusted properly for all other conditions, it would pop back just a little bit through the carb. Just a little "put,put" and not all of the time, when I released the throttle to shift. I could get it to go away by richening the mixure a bit but then it was just a bit too rich to idle really smooth. I had an original AirMaze air cleaner that I put on, it totally took care of the problem. I know some people claim it will make the engine run rich but I now run the GAV 1/4 or less with NO popping and no rich idle. Plus, running down the gravel roads here, I have an air cleaner.
