The earlier Magnum .40, .46. and .53 XL carbs wont fit on the new .52.
The spigot is smaller on the old carbs, they use the cinch bolt....and
the spigot (nounting flange) is shorter. Also they are not drilled for the
two screw carb hold.
Actually I have a recent 46 XLS engine. So that carb should work on the 52 XLS, no?
Trying to fill the old hole with JB weld and re-tapping the threads to stock
may or may not work....
Actually I thought of just filling the hole, no retapping.
