Do you think if somebody has a 360 and they buy a new 650 they should have to take it apart and epoxy/drill so it works? if you accept that, then you can but I don't. This is why problems don't get resolved, because people put it on the car owner. There is reasonable tuning for each carb to the car, like jetting, pump shot, mixture screws. But if I need epoxy and a drill, then there is a manufacturing flaw. Period.
