To do it properly requires a Dremel. So if you haven't got one, maybe you should save that money for college. But let's assume you've got one, and a conical sanding bit. It took me about 2 hours from start to finish, broken up between 2 days because the epoxy putty needs to dry thoroughly.

There are several decent mod guides like this one, but it pretty much involves gutting the Air Restrictor, then glomming on a bunch of epoxy putty, letting it dry, then sanding down the new AR assembly into a choke.

You don't have to go any further than step 5 to see a dramatic increase in performance. But if you augment the spring, you'll see a huge difference in performance.
