8639 - SOLD EACH - 60/5 slide for PHM carbs. These are for NEW STYLE carbs with the shallow float bowl nut which requires a 21mm spanner. They can be used on the older style carbs which have a deep float bowl nut and require a 14mm spanner but you *might* have to machine a bit of material [less than 1mm] from the bottom of the slide in the area that the slide screw touches the slide. Unfortunately, DELLORTO will not produce any of the slides for the old style carbs, they tell me to 'sell my customers a new set of carbs'.....
