Not sure but I think it seems it may be just a lean mixture issue..if its not air leaks it might be a blocked carby jet. Sometimes a bit of dirt may get inside the carby and block the main jet causing a lean mixture, can be fixed simply by cleaning the carby with a strong cleaner. Also the nuts connecting on the inlet of cylinder I find they get loose alot so they always have to be fairly tight.. I would try a richer mixture to see if it changes things...
