It sounds to me like the passages in your carburetor to the main jet need cleaning. Like I said earlier, it's difficult to clean these. I have used a single strand of small stranded copper wire and carb cleaner to rout out these internal passages. Cleaning them out is not easy. A total disassembly of the carb is needed to be able to get to them all. To assure that you have each clean, see if compressed air will flow through it after the cleaning. If not, you have more cleaning to do. A soaking will get all but these passages clean. Well, maybe a week of soaking might do it, but I was never patient enough for that.
