|Does your W/H tend to burst fire on the semi-auto setting? Odds are that the rocker or the pivot pin holes aren't in quite the right location. Most frequently the pivot pin hole is out of vertical alignment (usually too low). There are two solutions. First, build up the top of the rocker with weld and then re-shape it to its 0 original profile (effectively raising it up into contact with the bolt's T- slot while on the semi-auto setting). At the same time make sure that the rocker isn't too tall now so it doesn't contact the bolt while on the full-auto setting. This approach allows you to save your original W/H trigger housing but will keep you from being able to drop-in an unmodified replacement rocker in the future. Second, if the pivot pin hole is also out of front-to-rear or left-to-right alignment, the easiest fix is to completely replace the W/H trigger housing with one from a WW II GI parts set. The GI housing was gauged when it was made for correct dimensions - I'm not sure that can be said of all of the West Hurley production guns.|
This seems to be the problem you are talking about...

I don't know what a "good" rocker pivot is supposed to look like--is this one too worn?
If I do need to start changing out parts, can anyone recommend a good, detailed guide for disassembling the lower receiver? Thanks.

The internal parts are not that hard to get nor too expensive if you need to replace them. I can't tell if they need it by the photos.

If weak ammo is used, the bolt will not be driven back far enough to catch the sear. If something is hindering the recoil spring (such as kinks or debris in the bolt hole) it could slow the bolt. A bent or twisted receiver could also. A bent magazine might impede bolt movement.
It sounds like you need to get the instruction needed to completely disassemble the gun and clean it thoroughly (a CD is available from this board). Look for things that are obviously wrong. If the problem persists, get some hands on help.

I know I have encountered this sort of thing and created a detailed post along with many others people.
