All you may need to do is unscrew a little thing on the bottom (maby on the side, can't remember for sure) that looks like a bolt. take it out, blow it out with an air hose and put it back in. sometimes you won't even see what was in it but each time i have done this it has taken care of the surge problem. I had no need to take the carb off.

I did this and at first I thought problem was solved. But as I ran the engine longer and got it warmed up a bit with the choke open the surging started again. Temps will be near 40 tomorrow so perhaps removal is the project of the day.
