I broke a bolt in the throttle arm on #2 in my 76 CB550F and the new bolt doesn't sit right after drilling out the old one. Basically the piston doesn't sit low enough and I can't get a proper sync. So I need a throttle arm and the cylindrical piece inside that also has a hole. (pics attached) Do these parts readily go in and back out? I believe I can take apart the carbs and put in a throttle arm and cylindrical from another #2 or #4?
