Thanks for the replies. It is an old gasket, it’s just what I had, I’ll check the carb base for flatness, I checked the intake but not the carb. I’ll also get a new gasket. The symptoms are, fast, rough idle, dies when idled down, using a vacuum hose as a nozzle and carb and choke cleaner spray, I have the leak isolated to the sides of the carb base, seems ok along the front and back.
