Carby Grubee 50cc Carb Question

[carless]

does anyone know if the grubee 50cc with no intake carb, carb is a hl manufacture uses a different throttle. I recently bought this off a guy and I cannot get my old throttle or similar ones to fit in the carb. It's a fraction off and wont slide inside. so close but its making the whole engine worthless to me. carb is funny. no intake so not transferable
