That sound a bit like mine did before I got it set up right. I kept loosing one cylinder due to too much fuel. It sounds like yours may be picking up and dropping back to one cylinder. As suggested, maybe close you low speed needle a bit, take you plugs out and make sure they are clean and dry to start with. Once running, see if one cylinder stays cooler at the top. Once I leaned mine out, I had better results.
It was my first square tanker and until I had it figured out, I was wondering why anyone would want to mess with these 🙂
